     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a conductive member and particularly relates to a conductive member used as a touch panel. 
     The present invention also relates to a touch panel using a conductive member. 
     2. Description of the Related Art 
     In recent years, in various electronic devices including portable information devices such as tablet computers and smart phones, a touch panel which is used in combination with display devices such as liquid crystal display devices and which performs an input operation on an electronic device by causing members having tips thinner than those of fingers such as fingers and stylus pens to be in contact with or be close to a screen is in widespread. 
     In the touch panel, a conductive member in which a detection portion for detecting a touch operation by causing members having tips thinner than those of fingers such as fingers and stylus pens to be in contact with or be close to a transparent substrate is formed is used. 
     The detection portion is formed of a transparent conductive oxide such as Indium Tin Oxide (ITO), but is also formed of metal other than the transparent conductive oxide. Metal has advantages such as easy patterning, superior bending properties, and lower resistance compared to the above transparent conductive oxides, and thus metal such as copper or silver is used for conductive thin wires for the touch panels. 
     WO2015/060059A discloses a touch panel using metal fine wires. A touch panel of WO2015/060059A is an electrostatic capacitance sensor having a first conductive member formed of a plurality of first electrode patterns on a first substrate and a second conductive member formed of a plurality of second electrode patterns on a second substrate. The first electrode pattern and the second electrode pattern are respectively constituted by a plurality of cells having a substantially rhombic shape and are arranged along one direction on the first conductive member and the second conductive member. The first conductive member is layered on the second conductive member such that the plurality of first electrode patterns and the plurality of second electrode patterns are arranged along directions different from each other. 
     SUMMARY OF THE INVENTION 
     In a touch panel using a mesh pattern formed of such thin metal wires, in a case where a mesh pitch is set to a small value, parasitic capacitance of an electrode increases, and as a result, detection sensitivity of a touch position is lowered. 
     Meanwhile, in a case where the mesh pitch of the metal thin wires is increased in order to improve the detection sensitivity, a problem occurs in that a distance between the adjacent metal thin wires increases, the metal thin wires become more noticeable, and the visibility decreases. In a case where the mesh pitch of the thin metal wire is increased, a problem occurs in that moire caused by interference between a periodic thin pixel pattern of a display device used in combination with the touch panel and the thin metal wires becomes noticeable. 
     The present invention has been conceived in order to solve such problems in the related art, and has an object of providing a conductive member capable of improving the visibility and suppressing the generation of moire, even in a case where a detection electrode portion having a wide-pitch mesh pattern with a small parasitic capacitance and high detection sensitivity is used.

     It is preferable that each of the first mesh cell, the second mesh cell, and the third mesh cell each has a polygonal shape.

     Embodiment 1 
       FIG. 1  illustrates a configuration of a touch panel  2  in which a conductive member  1  according to Embodiment 1 of the present invention is used. 
     The touch panel  2  has a front surface  2 A and a back surface  2 B, and is used in a state in which a display device (not illustrated) such as a liquid crystal display device is arranged on the back surface  2 B side. The front surface  2 A of the touch panel  2  is a touch detection surface, and becomes a viewing side on which an operator of the touch panel  2  observes an image of the display device through the touch panel  2 . 
     The touch panel  2  has a transparent insulating cover panel  3  having a flat plate shape, which is arranged on the front surface  2 A, and the conductive member  1  is bonded to a surface of the cover panel  3  opposite to the front surface  2 A via a transparent adhesive  4 . 
     In the conductive member  1 , metal fine wires  6 A and metal fine wires  6 B are respectively formed on both surfaces of a transparent insulating substrate  5  which is a transparent insulating member. That is, in the conductive member  1 , a plurality of first electrodes  11  formed of the metal fine wires  6 A and a plurality of second electrodes  21  formed of the metal fine wires  6 B are arranged to face with each other in an insulation state. 
     The transparent insulating substrate  5  has a first surface  5 A that faces the front surface  2 A side of the touch panel  2  and a second surface  5 B that faces the back surface  2 B side of the touch panel  2 , and the metal fine wires  6 A is formed on the first surface  5 A, and the metal fine wires  6 B are formed on the second surface  5 B. As illustrated in  FIG. 1 , for the purpose of flattening or protecting the flattened metal fine wires  6 A and the metal fine wires  6 B, so as to cover the metal fine wires  6 A and the metal fine wires  6 B, transparent protective layers  7 A and  7 B are respectively arranged on the first surface  5 A and the second surface  5 B of the transparent insulating substrate  5 . 
     As illustrated in  FIG. 2 , in the conductive member  1 , a transmissive region S 1  is partitioned, and an edge part region S 2  is partitioned on the outside of the transmissive region S 1 . 
     The plurality of first electrodes  11  which are constituted by the metal fine wires  6 A, respectively extend along a first direction D 1 , and are arranged in juxtaposition with a second direction D 2  orthogonal to the first direction D 1  are formed on the first surface  5 A of the transparent insulating substrate  5 , and the plurality of second electrodes  21  which are constituted by the metal fine wires  6 B, respectively extend along the second direction D 2 , and are arranged in juxtaposition with the first direction D 1  are formed on the second surface  5 B of the transparent insulating substrate  5 . In this manner, the plurality of first electrodes  11  and the plurality of second electrodes  21  are arranged via the transparent insulating substrate  5 . 
     The first electrodes  11  formed on the first surface  5 A (viewing side) of the transparent insulating substrate  5  and the second electrodes  21  formed on the second surface  5 B (display device side) of the transparent insulating substrate  5  are arranged on the transmissive region S 1  so as to intersect with each other in plan view in an overlapping manner. 
     Meanwhile, a plurality of first edge part wires  12  connected to the plurality of first electrodes  11  are formed on the first surface  5 A of the transparent insulating substrate  5  in the edge part region S 2 . A plurality of first external connection terminals  13  are formed in an array in an edge portion of the transparent insulating substrate  5 , and the first connector portions  14  are formed on end portions of the first electrodes  11 . One end portions of the corresponding first edge part wires  12  are connected to first connector portions  14 , and the other end portions of the first edge part wires  12  are connected to the corresponding first external connection terminals  13 . Here, in the first electrodes  11 , a first connector portion may be formed also in the other end portion to which the first edge part wire  12  is not connected. The first connector portion formed in the other end portion of the first electrode  11  can be used as a terminal that connects the first edge part wires  12  and can be used as a terminal for a continuity test of the first electrode  11 . 
     In the same manner, a plurality of second edge part wires  22  that are connected to the plurality of second electrodes  21  are formed on the second surface  5 B of the transparent insulating substrate  5  in the edge part region S 2 . The plurality of second external connection terminals  23  are formed in an array in the edge portion of the transparent insulating substrate  5 , and second connector portions  24  are respectively formed in the end portions of the second electrodes  21 . One end portions of the corresponding second edge part wires  22  are connected to the second connector portions  24 , and the other end portions of the second edge part wires  22  are connected to the corresponding second external connection terminals  23 . Here, in the second electrode  21 , a second connector portion may be also formed in the other end portion to which the second edge part wire  22  is not connected. The second connector portion formed in the other end portion of the second electrode  21  can be used as a terminal for connecting the second edge part wire  22  or can be used as a terminal for a continuity test of the second electrodes  21 . 
       FIG. 3  illustrates a partial plan view of only the first electrode  11  in a region R 0  in an electrode intersection portion, in which the first electrodes  11  and the second electrodes  21  are overlapped with each other, seen from viewing side. The region R 0  in the electrode intersection portion is a region in which, in a case where the conductive member  1  is seen in a direction orthogonal to the first direction D 1  and the second direction D 2 , the first electrodes  11  and the second electrodes  21  are overlapped with each other. 
     The first electrode  11  has first detection electrode portions  11 A which are drawn by relatively thick lines in  FIG. 3  and dummy pattern portions  11 B in the first electrode which are drawn by relatively thin lines in  FIG. 3 . The first detection electrode portions  11 A and the dummy pattern portions  11 B in the first electrode are respectively formed of metal fine wires M 1 A and metal fine wires M 1 B, and the dummy pattern portions  11 B in the first electrode are arranged so as to be not electrically connected to the first detection electrode portions  11 A and be insulated from the first detection electrode portions  11 A. 
     The first detection electrode portion  11 A forms a first mesh pattern MP 1 . The first mesh pattern MP 1  is a mesh pattern having a first mesh pitch PA 1  which is formed by using rhombic first mesh cells C 1  as constitutional units and electrically connecting the plurality of first mesh cells C 1 . Here, the first mesh pitch PA 1  is defined as an average value of a distance P 1  in the first direction D 1  between centers of gravity of the first mesh cells C 1  adjacent to each other in the first direction D 1 . As illustrated in  FIG. 3 , in a case where the first mesh pattern MP 1  is a pattern constituted by the first mesh cells C 1  having the same shape, PA 1 =P 1 . In view of decreasing a parasitic capacitance of the first detection electrode portion  11 A and improving the sensitivity of a touch panel, the first mesh pitch PA 1  is preferably 500 μm or more. 
     As illustrated in  FIG. 4 , the dummy pattern portions  11 B in the first electrode having at least one first dummy unit pattern T 1 B are arranged inside of the first mesh cells C 1  of the first mesh pattern MP 1 . The first dummy unit pattern T 1 B is a pattern which forms the dummy pattern portions  11 B in the first electrode and in which the plurality of metal fine wires M 1 B not having intersection are arranged so as to be spaced from each other, that is, a pattern that does not include the metal fine wires M 1 B that intersect with each other in a cross shape. As illustrated in  FIG. 3 , the dummy pattern portions  11 B in the first electrode are preferably arranged inside all of the first mesh cells C 1 . 
     As illustrated in  FIG. 5 , in order to secure visibility, it is desirable that a line width W 1 A of the metal fine wires M 1 A that form the first detection electrode portions  11 A and a line width W 1 B of the metal fine wires M 1 B that form the dummy pattern portions  11 B in the first electrode is set, for example, in the range of 0.5 μm to 5 μm. In the present specification, the expression “to secure visibility” means that, in a case where the conductive member  1  is used in the touch panel  2  illustrated in  FIG. 1 , the presence of the metal fine wires M 1 A and M 1 B is not observed with bare eyes, and an image of a display device (not illustrated) is clearly checked through the conductive member  1 . 
     The line width W 1 A of the metal fine wires M 1 A that form the first detection electrode portions  11 A and the line width W 1 B of the metal fine wires M 1 B that form the dummy pattern portions  11 B in the first electrode are preferably the same value with each other, but may be different from each other. 
     In  FIG. 3 , there are a plurality of false intersection points that are seen as the metal fine wires M 1 A that form the first detection electrode portions  11 A and the metal fine wires M 1 B that form the dummy pattern portions  11 B in the first electrode intersect with each other, but, as illustrated in  FIGS. 4 and 5 , even in the false intersection points, in order to secure insulating properties, the metal fine wires M 1 A and the metal fine wires M 1 B are spaced from each other to have first gaps G 1 A and are not in contact with each other. Therefore, the metal fine wires M 1 A that form the first detection electrode portions  11 A and the metal fine wires M 1 B that form the dummy pattern portions  11 B in the first electrode are formed on the same surface (the first surface  5 A) of the transparent insulating substrate  5  but are in a state of being electrically insulated from each other. As illustrated in  FIG. 4 , the first electrode  11  has a portion in which the metal fine wire M 1 A and the metal fine wire M 1 B are spaced from each other by a second gap G 1 B that is longer than the first gap G 1 A. The first gap G 1 A between the metal fine wire M 1 A and the metal fine wire M 1 B preferably has a length of 0.5 μm or more and more preferably has a length of 5 μm to 25 μm. Otherwise, the first gap G 1 A preferably has a length of 1/2,000 or more of a length of one side of the first mesh cell C 1  and more preferably has a length of 1/200 to 1/40. Here, the length of the first gap G 1 A is defined by a distance of a line extending the metal fine wire M 1 B that form the dummy pattern portion  11 B in the first electrode in a straight line shape from an end portion of the metal fine wire M 1 B to an intersection with the metal fine wire M 1 A that forms the first detection electrode portions  11 A. The second gap G 1 B preferably has a length of 100 μm or more and more preferably has a length of 150 μm or more. Otherwise, the second gap G 1 B preferably has a length of 1/10 or more of a length of one side of the first mesh cell C 1 , more preferably has a length of ⅕ or more, and even more preferably has a length of ¼ or more. In this manner, in a case where the second gap G 1 B has a length of 150 μm or more, it is possible to secure further insulating properties between the first detection electrode portion  11 A and the dummy pattern portion  11 B in the first electrode and improve detection sensitivity in a case where the conductive member  1  is used in the touch panel  2 . The length of the second gap G 1 B is defined by the same length as the first gap G 1 A. 
       FIG. 6  illustrates a partial plan view in which only the second electrode  21  in the region R 0  in the electrode intersection portion in which the first electrode  11  and the second electrode  21  are overlapped with each other is seen from a viewing side. 
     The second electrode  21  has second detection electrode portions  21 A drawn by relatively thick broken lines in  FIG. 6  and dummy pattern portions  21 B in the second electrode drawn by relatively thin broken lines in  FIG. 6 . The second detection electrode portions  21 A and the dummy pattern portions  21 B in the second electrode are respectively formed of metal fine wires M 2 A and metal fine wires M 2 B, and the dummy pattern portions  21 B in the second electrode are arranged so as be not electrically connected to the second detection electrode portions  21 A and be insulated from the second detection electrode portions  21 A. 
     The second detection electrode portions  21 A form a second mesh pattern MP 2 . In the same manner as the first mesh pattern MP 1 , the second mesh pattern MP 2  is a mesh pattern having a second mesh pitch PA 2  which is formed by using rhombic second mesh cells C 2  as constitutional units and electrically connecting the plurality of rhombic second mesh cells C 2  Here, the second mesh pitch PA 2  is defined by an average value of a distance P 2  between in the first direction D 1  centers of gravity of the second mesh cells C 2  that are adjacent to each other in the first direction D 1 . As illustrated in  FIG. 6 , in a case where the second mesh pattern MP 2  is a pattern constituted by the second mesh cells C 2  having the same shape. PA 2 =P 2  is satisfied. In view of decreasing a parasitic capacitance of the second detection electrode portion  21 A and improving the sensitivity of the touch panel, the second mesh pitch PA 2  is preferably 500 μm or more. 
     The second mesh pitch PA 2  can be determined by a value different from the first mesh pitch PA 1 , but it is preferable that the second mesh pitch PA 2  is the same as the first mesh pitch PA 1 , since the detection sensitivity of the first electrodes  11  and second electrodes  12  can be caused to be in the same level, and the detection sensitivity of the touch panel can be homogenized, and according to the aspect, the following description is made. 
     As illustrated in  FIG. 7 , the dummy pattern portions  21 B in the second electrode having second dummy unit patterns T 2 B are arranged in the second mesh cell C 2  of the second mesh pattern MP 2 . The second dummy unit pattern T 2 B is a pattern not including the metal fine wires M 2 B that intersect with each other in a cross shape. As in  FIG. 6 , the dummy pattern portions  21 B in the second electrode are preferably arranged inside all the second mesh cell C 2 . 
     As illustrated in  FIG. 8 , in order to secure the visibility, it is desirable that a line width W 2 A of the metal fine wire M 2 A that forms the second detection electrode portion  21 A and a line width W 2 B of the metal fine wire M 2 B that forms the dummy pattern portions  21 B in the second electrode are set in the range of 0.5 μm to 5 μm. 
     The line width W 2 A of the metal fine wire M 2 A that forms the second detection electrode portion  21 A and the line width W 2 B of the metal fine wire M 2 B that forms the dummy pattern portions  21 B in the second electrode are preferably the same with each other but may be different from each other. 
     In  FIG. 6 , there are a plurality of false intersection points in which the metal fine wires M 2 A that form the second detection electrode portions  21 A and the metal fine wires M 2 B that form the dummy pattern portions  21 B in the second electrode are observed to intersect with each other, but as illustrated in  FIGS. 7 and 8 , even in the false intersection points, in order to secure insulating properties from each other, the metal fine wires M 2 A and the metal fine wires M 2 B are spaced from each other via a first gap G 2 A and are not in contact with each other. Therefore, though the metal fine wires M 2 A that form the second detection electrode portions  21 A and the metal fine wires M 2 B that form the dummy pattern portions  21 B in the second electrode are formed on the same surface (the second surface  5 B) of the transparent insulating substrate  5 , but are electrically insulated from each other. As illustrated in  FIG. 7 , the metal fine wires M 2 A and the metal fine wires M 2 B have portions spaced by a second gap G 2 B which is longer than the first gap G 2 A. For example, the first gap G 2 A between the metal fine wire M 2 A and the metal fine wire M 2 B preferably has a length of 15 μm or more and more preferably has a length of 5 μm to 25 μm. Otherwise, the first gap G 2 A preferably has a length of 1/2,000 or more of a length of one side of the second mesh cell C 2  and more preferably a length of 1/200 to 1/40. Here, the length of the first gap G 2 A is defined by a distance of a line extending the metal fine wires M 2 B that form the dummy pattern portions  21 B in the second electrode in a straight line shape from an end portion of the metal fine wires M 2 B to an intersection with the metal fine wires M 2 A that forms the second detection electrode portions  21 A. The second gap G 2 B preferably has a length of 100 μm or more and more preferably has a length of 150 μm or more. Otherwise, the second gap G 2 B preferably has a length of 1/10 or more of a length of one side of the second mesh cell C 2 , more preferably a length of ⅕ or more, and even more preferably a length of ¼ or more. In this manner, by causing the second gap G 2 B to have a length of 150 μm or more, it is possible to secure further insulating properties between the second detection electrode portions  21 A and the dummy pattern portions  21 B in the second electrode, and it is possible to improve the detection sensitivity in a case of using the conductive member  1  in the touch panel  2 . The length of the second gap G 2 B can be defined by the same length of the first gap G 2 A. 
     Here, the second mesh pattern MP 2  is arranged in a position in which a peak of the first mesh cell C 1  and a peak of the second mesh cell C 2  are deviated by ¼ of the first mesh pitch PA 1  in the first direction D 1  such that a center of gravity of the first mesh cell C 1  and a peak of the second mesh cell C 2  are overlapped with each other, with respect to the first mesh pattern MP 1  Accordingly, in the region R 0  in the electrode intersection portion, in a case where the first electrodes  11  that are formed on the first surface  5 A of the transparent insulating substrate  5  and the second electrodes  21  that are formed on the second surface  5 B of the transparent insulating substrate  5  are observed on the viewing side, as illustrated in  FIG. 9 , the first detection electrode portions  11 A of the first electrodes  11  and the dummy pattern portions  11 B in the first electrode, and the second detection electrode portions  21 A of the second electrodes  21  and the dummy pattern portions  21 B in the second electrode are combined with each other, so as to form the third mesh pattern MP 3  constituted by rhombic third mesh cells C 3 . Specifically, a metal fine wire that forms the first mesh pattern MP 1  and a metal fine wire that forms the second mesh pattern MP 2  are arranged so as to be overlapped with each other in a dot shape. That is, the first mesh pattern MP 1  and the second mesh pattern MP 2  are not overlapped with each other in a line shape. By causing the patterns to be arranged so as to be overlapped with each other in a dot shape, it is possible to decrease the parasitic capacitance in the electrode intersection portion, it is possible to improve the detection sensitivity of the touch panel  2 . That is, the second mesh pattern MP 2  can be arranged at a position of being deviated by a distance ΔL in the first direction D 1  with respect to the first mesh pattern MP 1 . Particularly, it is preferable that the patterns are arranged such that the center of gravity of the first mesh cell C 1  and the peak of the second mesh cell C 2  are in different positions. According to this arrangement, the parasitic capacitance in the electrode intersection portion can be decreased, and the detection sensitivity of the touch panel can be improved. As illustrated in  FIG. 9 , it is preferable that relative positions of the first mesh pattern MP 1  and the second mesh pattern MP 2  are set such that an interval between the metal fine wire that forms the second mesh pattern MP 2  and the metal fine wire that is adjacent to this metal fine wire and forms the first mesh pattern MP 1  becomes ¼ of the first mesh pitch PA 1 . Accordingly, since the parasitic capacitance in the electrode intersection portion can be effectively decreased, and also the visibility can be improved, the detection sensitivity of the touch panel  2  in a case of using the conductive member  1  can be improved and the visibility can be improved. 
     A third mesh pattern MP 3  is a mesh pattern having a third mesh pitch PA 3  which is formed by using the rhombic third mesh cells C 3  as constitutional units. The third mesh cell C 3  may not be a cell shape that is completely closed and may have a structure having a gap (internal) in a portion of the cells. The length of the gap is 0.5 to 30 μm. 
     Here, the third mesh pitch PA 3  is defined by an average value of a distance P 3  in the first direction D 1  between centers of gravity of the third mesh cells C 3  that are adjacent to each other in the first direction D 1 . The third mesh pitch PA 3  has a value of ¼ of the first mesh pitch PA 1  and the second mesh pitch PA 2  of the first mesh pattern MP 1  and the second mesh pattern MP 2 . The third mesh pitch PA 3  can be ¼ or less of the first mesh pitch PA 1  and the second mesh pitch PA 2 . In this case, the third mesh pitch PA 3  is preferably ¼, ⅙, or ⅛ of the first mesh pitch PA 1  and the second mesh pitch PA 2  Particularly, in view of visibility of the metal fine wire and detection sensitivity of the touch panel, the third mesh pitch PA 3  is preferably ¼ of the first mesh pitch PA 1  and the second mesh pitch PA 2 . 
     In this manner, the first detection electrode portions  11 A of the first electrodes  11  formed on the first surface  5 A of the transparent insulating substrate  5  form the first mesh pattern MP 1 , the dummy pattern portions  11 B in the first electrode that are insulated from the first detection electrodes  11 A in the first mesh cells C 1  constituting the first mesh pattern MP 1  are arranged, the second detection electrode portions  21 A of the second electrodes  21  formed in the second surface  5 B of the transparent insulating substrate  5  form the second mesh pattern MP 2 , the dummy pattern portions  21 B in the second electrode that are insulated from the second detection electrode portion  21 A in the second mesh cell C 2  constituting the second mesh pattern MP 2  are arranged, and the first detection electrode portions  11 A of the first electrodes  11  and the dummy pattern portions  11 B in the first electrode are combined with the second detection electrode portions  21 A of the second electrodes  21  and the dummy pattern portions  21 B in the second electrode to form the third mesh pattern MP 3  constituting the third mesh cell C 3 . 
     Therefore, the first mesh pitch PA 1  of the first mesh pattern MP 1  that is formed by the first detection electrode portions  11 A of the first electrodes  11  that is used for the detection of a touch operation and the second mesh pitch PA 2  of the second mesh pattern MP 2  that is formed by the second detection electrode portions  21 A of the second electrodes  21  can be set to be longer than the third mesh pitch PA 3  of the third mesh pattern MP 3 . In Embodiment 1, the first mesh pitch PA 1  and the second mesh pitch PA 2  are as large as four times the third mesh pitch PA 3 . 
     Accordingly, in a case of being seen from the viewing side, the interval of the adjacent metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B can be narrowed down such that the presence of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B become invisible, and the size and the angle of the third mesh cell C 3  are selected to design the third mesh pattern MP 3  such that the generation of the moire in a case of using a display device (not illustrated) in combination with the touch panel  2  is decreased. Therefore, the parasitic capacitances of the first detection electrode portions  11 A and the second detection electrode portions  21 A can be reduced. In this manner, even in a case of using a detection electrode portion having less parasitic capacitance, high detection sensitivity, and a mesh pattern with a wide pitch, for example, a wide pitch of 500 μm or more, together with improving the visibility, the generation of the moire in a case of combining the touch panel  2  and a display device can be suppressed. 
     Though not illustrated, a configuration of having a dummy electrode electrically insulated from the first detection electrode portions  11 A of these first electrodes  11  in a region between the first electrodes  11  adjacent to each other which are arranged in juxtaposition on the first surface  5 A of the transparent insulating substrate  5  and having a dummy electrode electrically insulated from the second detection electrode portions  21 A of these second electrodes  21  in the region between the second electrodes  21  adjacent to each other which are arranged in juxtaposition on the second surface  5 B of the transparent insulating substrate  5 . At this point, the first electrode  11  can have a disconnected portion for insulating the first detection electrode portion  11 A and the dummy electrode, and the second electrode  21  can have a disconnected portion for insulating the second detection electrode portion  21 A and the dummy electrode. 
     The dummy electrode that is positioned between the first electrodes  11  adjacent to each other is formed of a metal fine wire to have a pattern by the first detection electrode portions  11 A of the first electrodes  11  and the dummy pattern portions  11 B in the first electrode as illustrated in  FIG. 3 . The dummy electrode that is positioned between the plurality of second electrodes  21  is formed of a metal fine wire having a pattern by the second detection electrode portions  21 A of the second electrodes  21  and the dummy pattern portions  21 B in the second electrode as illustrated in  FIG. 6 . 
     Each of the disconnection widths of the disconnected portion for insulating the first detection electrodes  11 A and the dummy electrode and the disconnected portion for insulating the second detection electrode portion  21 A and the dummy electrode is preferably 0.5 to 30 μm. A disconnected portion may be further provided in the metal fine wire inside the dummy electrode. For example, one or more disconnected portions may be provided to each side of the mesh cell constituting the dummy electrode. 
     In a case where such a dummy electrode is formed on each of the first surface  5 A and the second surface  5 B of the transparent insulating substrate  5 , in a case of being seen from the viewing side, not only on the electrode intersection portion in which the first electrodes  11  and the second electrodes  21  are overlapped with each other, but also on the entire surface of the transmissive region S 1 , the third mesh pattern MP 3  illustrated in  FIG. 9  is formed, such that the pattern appearance of the first electrodes  11  and the second electrodes  21  can be prevented, and also the improvement of the visibility and the decrease of the moire generation can be realized. 
     In the above, a configuration in which the first electrodes  11  and the second electrodes  21  formed of metal fine wires are arranged on both surfaces of the transparent insulating substrate  5  illustrated in  FIG. 1  is described, but the present invention is not limited to the configuration. The present invention may have a configuration in which the first electrodes  11  and the second electrodes  21  are insulated from the transparent insulating member, may be a configuration in which two sheets of electrode substrates illustrated in FIG. 11 of JP2016-126731A are bonded via a transparent pressures sensitive adhesive layer, or may be a configuration in which column wires and row wires are provided on a transparent substrate via an interlayer insulation film as illustrated in FIG. 4 of JP2010-097536A. In the former case, the electrode substrate and the transparent pressure sensitive adhesive layer constitute the transparent insulating member, and in the latter case, the interlayer insulation film corresponds to the transparent insulating member. 
     Hereinafter, each member constituting the conductive member  1  is described. 
     &lt;Transparent Insulating Substrate&gt; 
     The transparent insulating substrate  5  is not particularly limited, as long as the transparent insulating substrate is transparent, has electric insulation properties, and supports the first electrodes  11  and the second electrodes  21 , but as the material constituting the transparent insulating substrate  5 , for example, tempered glass, alkali free glass, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), a cyclo-olefin polymer (COP), a cyclic olefin copolymer (COC), polycarbonate (PC), an acrylic resin, polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), and triacetate cellulose (TAC) can be used. The thickness of the transparent insulating substrate  5  is, for example, 20 to 1,000 μm, and particularly preferably 30 to 100 μm. 
     The total light transmittance of the transparent insulating substrate  5  is preferably 40% to 100%. The total light transmittance is measured by using “plastic—a method of obtaining total light transmittance and total light reflectance” regulated in JIS K 7375:2008. 
     One of the preferred embodiments of the transparent insulating substrate  5  is a treated substrate that has been subjected to at least one treatment selected from the group consisting of an atmospheric pressure plasma treatment, a corona discharge treatment, and an ultra violet irradiation treatment. By performing the above treatment, a hydrophilic group such as an OH group is introduced to the front surface of the treated transparent insulating substrate  5 , and adhesiveness between the first electrodes  11  and the second electrodes  21  is improved. Among the above treatments, in view of improving the adhesiveness between the first electrodes  11  and the second electrodes  21 , an atmospheric pressure plasma treatment is preferable. 
     Another preferred aspect of the transparent insulating substrate  5  preferably has undercoat layers including polymers on the first surface  5 A on which the first electrodes  11  are formed and the second surface  5 B on which the second electrodes  21  are formed. In a case where photosensitive layers for forming the first electrode  11  and the second electrode  21  are formed on this undercoat layer, adhesiveness between the first electrode  11  and the first surface  5 A and between the second electrode  21  and the second surface  5 B are further improved. 
     The method of forming the undercoat layer is not particularly limited, but examples thereof include a method of coating a substrate with a composition for forming an undercoat layer including a polymer, and performing a heat treatment, if necessary. The composition for forming an undercoat layer may include a solvent, if necessary. The types of the solvent are not particularly limited, but examples thereof include a solvent used in the composition for forming a photosensitive layer described below. A latex including polymer fine particles as the composition for forming an undercoat layer including a polymer may be used. The refractive index of the undercoat layer may be adjusted so as to use the undercoat layer as a refractive index adjusting layer for decreasing the reflection of the transparent insulating substrate  5 . 
     The thickness of the undercoat layer is not particularly limited, but in view of causing the adhesiveness of the first electrode  11  and the second electrode  21  with the transparent insulating substrate  5  to be excellent, the thickness is preferably 0.02 to 0.3 μm and more preferably 0.03 to 0.2 μm. 
     If necessary, the conductive member  1  may include an antihalation layer in addition to the above undercoat layer, as another layer between the transparent insulating substrate  5  and the first electrode  11  and the second electrode  21 . 
     &lt;Metal Fine Wire&gt; 
     With reference to  FIGS. 5 and 8 , as described above, in order to secure visibility, it is desirable that the metal fine wire M 1 A that forms the first detection electrode portion  11 A of the first electrode  11 , the metal fine wire M 1 B that forms the dummy pattern portions  11 B in the first electrode, the metal fine wire M 2 A that forms the second detection electrode portion  21 A of the second electrode  21 , and the metal fine wire M 2 B that forms the dummy pattern portions  21 B in the second electrode, for example, have a line width set in the range of 0.5 to 5 μm. In a case where the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B have such a line width, the first detection electrode portions  11 A and the second detection electrode portions  21 A which have low resistances can be comparatively easily formed. 
     The thicknesses of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B are not particularly limited, but the thickness is preferably 0.01 to 200 μm, more preferably 30 μm or less, even more preferably 20 μm or less, particularly preferably 0.01 to 9 μm, and most preferably 0.05 to 5 μm. Accordingly, the resistance reduction of the first detection electrode portion  11 A and the second detection electrode portion  21 A and improvement of the durability of the first detection electrode portions  11 A, the dummy pattern portions  11 B in the first electrode, the second detection electrode portions  21 A, and the dummy pattern portions  21 B in the second electrode can be comparatively easily realized. 
     The metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B use metal or alloy as a forming material and can be formed of, for example, copper, aluminum, or silver. It is preferable that the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B include metallic silver, but may include metals other than metallic silver such as gold and copper. It is preferable that the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B include metallic silver, gelatin, and a polymer binder such as an acry⋅styrene-based latex, which are suitable for forming a mesh pattern. As the materials of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B, metal such as copper, aluminum, silver, molybdenum, or titanium, or an alloy containing these is preferably used. The metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B may have a lamination layer structure of these metal materials, for example, a metal fine wire having a lamination layer structure of molybdenum/aluminum/molybdenum or a metal fine wire having a lamination layer structure of molybdenum/copper/molybdenum can be used. 
     For example, the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B may include metal oxide particles, a metal paste such as a silver paste and a copper paste, and metal nanowire particles such as silver nanowires and copper nanowires. 
     In order to improve the visibility of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B, a blackening layer may be formed at least on the viewing, side surface of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B. As the blackening layer, metal oxide, metal nitride, metal oxynitrides, and metal sulfide and the like are used, and typically, copper oxynitride, copper nitride, copper oxide, molybdenum oxide, and the like can be used. 
     The sizes of the first mesh pitch PA 1  of the first mesh pattern MP 1  that forms the first detection electrode portion  11 A of the first electrode  11  and the second mesh pitch PA 2  of the second mesh pattern MP 2  that forms the second detection electrode portion  21 A of the second electrode  21  are not particularly limited, but in view of improving the detection sensitivity capable of decreasing the parasitic capacitance of the first electrode  11  and the second electrode  21 , the size is preferably 500 μm or more, more preferably 600 μm or more, and even more preferably 800 μm or more. The upper limit values of the first mesh pitch PA 1  and the second mesh pitch PA 2  is a width of the first electrode and a width of the second electrode and is preferably 1,600 μm or less. It is preferable that the mesh pitch is in the range of not exceeding the upper limit value, because the conduction of the electrode as the touch panel can be sufficiently secured. The size of the third mesh pitch PA 3  of the third mesh pattern MP 3  that is formed by combining the first detection electrode portions  11 A of the first electrodes  11  the dummy pattern portions  11 B in the first electrode, the second detection electrode portions  21 A of the second electrodes  21 , and the dummy pattern portions  21 B in the second electrode with each other is not particularly limited, but in consideration of visibility, the size is preferably 50 to 400 μm and more preferably 150 to 300 μm. 
     In view of suppressing the moire of the display device, the first mesh cell C 1  as the constitutional unit of the first mesh pattern MP 1 , the second mesh cell C 2  as the constitutional unit of the second mesh pattern MP 2 , and the third mesh cell C 3  as the constitutional unit of the third mesh pattern MP 3  are preferably quadrangular shapes and particularly preferably rhombuses. The size of the acute angle of this rhombus can be, for example, 20 degrees to 88 degrees. The size of the acute angle of this rhombus is preferably 30 degrees to 85 degrees and more preferably 50 degrees to 80 degrees. The first mesh cell C 1 , the second mesh cell C 2 , and the third mesh cell C 3  may be regular hexagons, regular triangles, and other polygons, other than rhombuses. It is preferable that the first mesh pattern MP 1 , the second mesh pattern MP 2 , and the third mesh pattern MP 3  are respectively constituted by the plurality of first mesh cells C 1  having the same shape, the plurality of second mesh cells C 2  having the same shape, and the plurality of third mesh cells C 3  having the same shape, because the design of the mesh patterns of the electrodes becomes easy. It is particularly preferable that the first mesh cells C 1  and the second mesh cells C 2  have the same shape, because the design of the mesh patterns of the electrodes becomes easy. 
     The third mesh pattern MP 3  illustrated in  FIG. 9  is a regular fixed pattern in which the plurality of third mesh cells C 3  having the same shape are repeatedly arranged in the first direction D 1  and the second direction D 2 , respectively, but the present invention is not limited thereto and may be an irregular pattern formed of the irregularly shaped third mesh cells C 3 . 
     The third mesh pattern MP 3  has a polygonal shape having lengths of irregular sides of −10% to +10%, particularly, an irregular shape constituted by the quadrangular third mesh cells, with respect to the average value of the lengths of the sides of the plurality of third mesh cells C 3  constituting the third mesh pattern MP 3 . According to this configuration, it is possible to achieve both moire suppression and color noise reduction in a case of being combined with a display device. 
     In a case of calculating the average value of the lengths of the sides of the plurality of third mesh cells C 3 , an average value of the lengths of the sides with respect to the plurality of third mesh cells C 3  arranged in the area having the defined area can be calculated. For example, it is preferable to calculate the average value of the side length with respect to the plurality of third mesh cells C 3  arranged in a region of 10 mm×10 mm. 
     In order to cause the third mesh pattern MP 3  to be such an irregular pattern, the third mesh pattern MP 3  can also be formed by using the first mesh pattern MP 1  formed by the plurality of first mesh cells C 1  having irregular shapes and the second mesh pattern MP 2  formed by the plurality of second mesh cells C 2  having irregular shapes. In this case, the first mesh pitch PA 1  of the first mesh pattern MP 1  can be defined by an average value of the distance in the first direction between centers of gravity of two first mesh cells C 1  adjacent to each other in the first direction. The second mesh pitch PA 2  of the second mesh pattern MP 2  can be defined by the average value of the distances in the first direction between centers of gravity of two second mesh cells C 2  adjacent to each other in the first direction. 
     In a case of calculating the average value of the distances between the centers of gravity of the mesh cells adjacent to each other, with respect to the plurality of first mesh cells C 1  and the plurality of second mesh cells C 2  arranged in the region having a predetermined area, an average value of the distances between the centers of gravity of the mesh cells adjacent to each other can be calculated. For example, it is preferable to calculate the average value of the distances between the centers of gravity of the mesh cells adjacent to each other of the plurality of first mesh cells C 1  and the plurality of second mesh cells C 2  arranged in the region of 10 mm×10 mm. 
     Also by causing the sizes or shapes (including angles) of the first mesh cells C 1  as the constitutional units of the first mesh pattern MP 1  and the second mesh cell C 2  as the constitutional unit of the second mesh pattern MP 2  to be different from each other, it is possible to constitute the third mesh pattern MP 3  formed by the plurality of third mesh cells C 3  having an irregular shape. 
     Subsequently, the method of forming the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B is described. As the method of forming these metal fine wires, for example, a plating method, a silver salt method, a vapor deposition method, a printing method, and the like can be suitably used. 
     The method of forming the metal fine wires by the plating method is described. For example, the fine metal wire can be constituted by using a metal plating film formed on the underlayer by performing electroless plating on the electroless plating underlayer. In this case, the metal fine wires are formed by forming a pattern shape on the substrate with catalyst ink containing at least metal fine particles, then immersing the substrate in an electroless plating bath, and forming a metal plating film. More specifically, the method for manufacturing a metal-coated substrate disclosed in JP2014-159620A can be used. The metal fine wires are formed by forming a pattern shape on the substrate with a resin composition having at least a functional group capable of interacting with a metal catalyst precursor, applying a catalyst or a catalyst precursor, immersing the substrate in an electrolessly plate bath, and forming a metal plating film. More specifically, the method of manufacturing a metal-coated substrate disclosed in JP2012-144761A can be applied. 
     The method of forming metal thin lines by the silver salt method is described. First, an exposure treatment is performed on a silver halide emulsion layer including silver halide by using an exposure pattern to be metal fine wires, and then a development treatment is performed, so as to form the fine metal wires. More specifically, methods of manufacturing metal fine wires disclosed in JP2012-006377A, JP2014-112512A, JP2014-209332A, JP2015-022397A, JP2016-192200A, and WO2016/157585A can be used. 
     The method of forming metal thin wires by the vapor deposition method is described. First, a copper thin layer can be formed by vapor deposition, and copper wires are formed of the copper thin layer by photolithography, so as to form metal fine wires. In addition to the vapor deposited copper thin layer, an electrolytic copper thin layer can be used as the copper thin layer. More specifically, a step of forming copper wires disclosed in JP2014-029614A can be used. 
     The method of forming the metal thin wire by the printing method is described. First, a conductive paste containing conductive powders is applied to a substrate so as to have the same pattern as the metal thin wires, and then the heat treatment is performed, so as to form the metal thin wires. In the pattern formation by using a conductive paste, for example, an inkjet method or a screen printing method can be used. More specifically, a conductive paste disclosed in JP2011-028985A can be used as the conductive paste. 
     &lt;Protective Layer&gt; 
     As the transparent protective layers  7 A and  7 B, organic films of gelatin, an acrylic resin, a urethane resin, or the like, and inorganic films of silicon dioxide or the like can be used, and the film thickness is preferably 10 nm to 100 nm. 
     If necessary, a transparent coating layer may be formed on the protective layer. As the transparent coat layer, an organic film of an acrylic resin, a urethane resin, or the like is used, and the film thickness thereof is preferably 1 μm to 100 μm. 
     As a material of the cover panel  3  constituting the touch panel  2 , tempered glass, polycarbonate, polyethylene terephthalate, polymethyl methacrylate resin (PMMA), or the like can be used, and the thickness of the cover panel  3  is preferably 0.1 to 1.5 mm. A decorative layer that shields the edge part region S 2  may be formed on the cover panel  3 . 
     As the transparent adhesive  4  for bonding the conductive member  1  to the cover panel  3 , an optical transparent pressures sensitive adhesive sheet (Optical Clear Adhesive: OCA) or an optical transparent pressures sensitive adhesive resin (Optical Clear Resin: OCR) can be used, and the preferable film thickness is 10 μm to 200 μm. As the optical transparent pressures sensitive adhesive sheet, for example, 8146 series manufactured by The 3M Company can be used. 
     &lt;Edge Part Wire Insulating Film&gt; 
     For the purpose of preventing shorting between edge part wires and corrosion of the edge part wires, an edge part wire insulating film may be formed on the first edge part wires  12  and the second edge part wires  22  as illustrated in  FIG. 2 . As the edge part wire insulating film, an organic film of an acrylic resin, a urethane resin, or the like is used, and the film thickness is preferably 1 μm to 30 μm. The edge part wire insulating film may be formed only on one of the first edge part wires  12  and the second edge part wires  22 . 
     Embodiment 2 
     In Embodiment 1 described above, the dummy pattern portions  11 B in the first electrode having the first dummy unit pattern T 1 B illustrated in  FIG. 4  are arranged inside each mesh of the first mesh pattern MP 1  formed of the first detection electrode portions  11 A, and the dummy pattern portions  21 B in the second electrode having the second dummy unit pattern T 2 B illustrated in  FIG. 7  are arranged inside each mesh of the second mesh pattern MP 2  formed of the second detection electrode portions  21 A, but the first dummy unit pattern T 1 B and the second dummy unit pattern T 2 B are not limited to those illustrated in  FIGS. 4 and 7 . 
       FIG. 10  illustrates a partial plan view of only a first electrode  31  in an electrode intersection portion of a conductive member according to Embodiment 2 seen from a viewing side. The first electrode  31  is formed on the first surface  5 A of the transparent insulating substrate  5  illustrated in  FIG. 1 . 
     The first electrode  31  has first detection electrode portions  31 A which are drawn by relatively thick lines in  FIG. 10  and dummy pattern portions  31 B in the first electrode which are drawn by relatively thin lines in  FIG. 10 . The first detection electrode portions  31 A and the dummy pattern portions  31 B in the first electrode are respectively formed of the metal fine wires M 1 A and the metal fine wires M 1 B, and the dummy pattern portions  31 B in the first electrode are arranged so as to be not electrically connected to the first detection electrode portions  31 A and insulated from the first detection electrode portions  31 A. 
     In the same manner as the first detection electrode portions  11 A in Embodiment 1, the first detection electrode portions  31 A form the first mesh pattern MP 1  having the first mesh pitch PA 1  to which the plurality of first mesh cells C 1  are electrically connected, by using the rhombic first mesh cells C 1  as constitutional units. 
     The dummy pattern portions  31 B in the first electrode having at least one third dummy unit pattern T 3 B as illustrated in  FIG. 11  are arranged inside the first mesh cells C 1  of the first mesh pattern MP 1 . The metal fine wires M 1 B constituting the dummy pattern portions  31 B in the first electrode and the metal fine wires M 1 A constituting the first mesh cells C 1  are spaced by the first gap G 1 A and the second gap G 1 B which is longer than the first gap G 1 A. 
       FIG. 12  illustrates a partial plan view of only a second electrode  41  in the electrode intersection portion of the conductive member according to Embodiment 2 seen from a viewing side. The second electrode  41  is formed on the second surface  5 B of the transparent insulating substrate  5  illustrated in  FIG. 1 . 
     The second electrode  41  has second detection electrode portions  41 A drawn by relatively thick broken lines in  FIG. 12  and dummy pattern portions  41 B in the second electrode drawn by relatively thin broken lines in  FIG. 12 . The second detection electrode portions  41 A and the dummy pattern portions  41 B in the second electrode are respectively formed of the metal fine wires M 2 A and the metal fine wires M 2 B, and the dummy pattern portions  41 B in the second electrode are arranged so as to be not electrically connected to the second detection electrode portions  41 A and insulated from the second detection electrode portions  41 A. 
     In the same manner as the first mesh pattern MP 1 , the second detection electrode portions  41 A form the second mesh pattern MP 2  having the second mesh pitch PA 2  by using the rhombic second mesh cells C 2  as the constitutional units. 
     Also, the dummy pattern portions  41 B in the second electrode which has a fourth dummy unit pattern T 4 B as illustrated in  FIG. 13  are arranged inside the second mesh cell C 2  of the second mesh pattern MP 2 . The metal fine wires M 2 B constituting the dummy pattern portions  41 B in the second electrode and the metal fine wires M 2 A constituting the second mesh cells C 2  are spaced by the first gap G 2 A and the second gap G 2 B which is longer than the first gap G 2 A. 
     The third dummy unit pattern T 3 B and the fourth dummy unit pattern T 4 B used in Embodiment 2 have pattern shapes different from the first dummy unit pattern T 1 B and the second dummy unit pattern T 2 B in Embodiment 1 as illustrated in  FIGS. 4 and 7 . The third dummy unit pattern T 3 B is a pattern in which the metal fine wires M 1 B that form the dummy pattern portions  31 B in the first electrode intersect with each other in a cross shape, and the fourth dummy unit pattern T 4 B has points at which the metal fine wires M 2 B that form the dummy pattern portions  41 B in the second electrode intersect with each other in a cross shape. 
     Also in Embodiment 2, in the same manner as Embodiment 1, the second mesh pattern MP 2  is arranged so as to be deviated by ¼ of the first mesh pitch PA 1  such that a center of gravity of the first mesh cell C 1  and a peak of the second mesh cell C 2  are overlapped with each other, with respect to the first mesh pattern MP 1 . Accordingly, in the region R 0  in the electrode intersection portion, in a case where the first electrodes  31  and the second electrodes  41  are observed on the viewing side, as illustrated in  FIG. 14 , the first detection electrode portions  31 A of the first electrodes  31  and the dummy pattern portions  31 B in the first electrode, and the second detection electrode portions  41 A of the second electrodes  41  and the dummy pattern portions  41 B in the second electrode are combined with each other, so as to form the third mesh pattern MP 3  constituted by rhombic third mesh cells C 3 , in the same manner as in Embodiment 1. The second mesh pitch PA 2  has a value of ¼ of the first mesh pitch PA 1  and the second mesh pitch PA 2  of the first mesh pattern MP 1  and the second mesh pattern MP 2 . 
     In the same manner, even in a case where the dummy pattern portions  31 B in the first electrode that have the third dummy unit pattern T 3 B illustrated in  FIG. 11  are arranged inside the first mesh cells C 1  of the first mesh pattern MP 1 , and the dummy pattern portions  41 B in the second electrode that have the fourth dummy unit pattern T 4 B illustrated in  FIG. 13  are arranged inside the second mesh cell C 2  of the second mesh pattern MP 2 , the third mesh pattern MP 3  having the third mesh pitch PA 3  can be formed. 
     Therefore, the first mesh pitch PA 1  of the first mesh pattern MP 1  that is formed by the first detection electrode portions  31 A of the first electrodes  31  that is used for the detection of a touch operation and the second mesh pitch PA 2  of the second mesh pattern MP 2  that is formed by the second detection electrode portions  41 A of the second electrodes  41  can be set to be four times of the size of the third mesh pitch PA 2  of the third mesh pattern MP 3 . 
     Accordingly, in the same manner as in Embodiment 1, the presence of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B become invisible in a case of being observed on the viewing side, the sizes and the angles of the third mesh cell C 3  can be selected such that the generation of the moire is decreased in a case where the display device is used by being combined with the touch panel  2 , so as to design the third mesh pattern MP 3 , and thus the parasitic capacitances of the first detection electrode portions  31 A and the second detection electrode portions  41 A can be reduced. Therefore, even in a case where a detection electrode portion with a large mesh pattern having a wide pitch which has less parasitic capacitance and high detection sensitivity is used, the visibility can be improved, and also in a case where the touch panel  2  and the display device are combined with each other to be used, the generation of the moire can be suppressed.

     The first electrode  51  has first detection electrode portions  51 A which are drawn by relatively thick lines in  FIG. 15  and dummy pattern portions  51 B in the first electrode which are drawn by relatively thin lines in  FIG. 15 . The first detection electrode portions  51 A and the dummy pattern portions  51 B in the first electrode are respectively formed of the metal fine wires M 1 A and the metal fine wires M 1 B, and the dummy pattern portions  51 B in the first electrode are arranged so as to be not electrically connected to the first detection electrode portions  51 A and insulated from the first detection electrode portions  51 A. 
     In the same manner as the first detection electrode portions  11 A in Embodiment 1, the first detection electrode portions  51 A form the first mesh pattern MP 1  having the first mesh pitch PA 1  by using the rhombic first mesh cells C 1  as constitutional units and electrically connecting the plurality of first mesh cells C 1 . 
     Also, the dummy pattern portions  51 B in the first electrode which has a fifth dummy unit pattern T 5 B as illustrated in  FIG. 16  are arranged inside the first mesh cell C 1  of the first mesh pattern MP 1 . The metal fine wires M 1 B constituting the dummy pattern portions  51 B in the first electrode and the metal fine wires M 1 A constituting the first mesh cells C 1  are spaced by the first gap G 1 A. 
       FIG. 17  illustrates a partial plan view of only a second electrode  61  in the electrode intersection portion of the conductive member according to Embodiment 3 seen from a viewing side. The second electrode  61  is formed on the second surface  5 B of the transparent insulating substrate  5  illustrated in  FIG. 1 . 
     The second electrode  61  has second detection electrode portions  61 A drawn by relatively thick broken lines in  FIG. 17  and dummy pattern portions  61 B in the second electrode drawn by relatively thin broken lines in  FIG. 17 . The second detection electrode portions  61 A and the dummy pattern portions  61 B in the second electrode are respectively formed of metal fine wires M 2 A and metal fine wires M 2 B, and the dummy pattern portions  61 B in the second electrode are arranged so as be not electrically connected to the second detection electrode portions  61 A and be insulated from the second detection electrode portions  61 A. 
     In the same manner as the first mesh pattern MP 1 , the second detection electrode portions  61 A form the second mesh pattern MP 2  having the second mesh pitch PA 2  by using the rhombic second mesh cells C 2  as constitutional units and electrically connecting the plurality of second mesh cells C 2 . 
     Also, the dummy pattern portions  61 B in the second electrode which has a sixth dummy unit pattern T 6 B as illustrated in  FIG. 18  are arranged inside each mesh of the second mesh pattern MP 2 . The metal fine wires M 2 B constituting the dummy pattern portions  61 B in the second electrode and the metal fine wires M 2 A constituting the second mesh cells C 2  are spaced by the first gap G 2 A. 
     The fifth dummy unit pattern T 5 B and the sixth dummy unit pattern T 6 B used in Embodiment 3 have pattern shapes different from the first dummy unit pattern T 1 B and the second dummy unit pattern T 2 B in Embodiment 1 as illustrated in  FIGS. 4 and 7 . The fifth dummy unit pattern T 5 B and the sixth dummy unit pattern T 6 B have the shape identical to each other, and the metal fine wires M 1 B that form, the dummy pattern portions  51 B in the first electrode and the metal fine wires M 2 B that form the dummy pattern portions  61 B in the second electrode respectively have points at which the metal fine wires intersect with each other in a cross shape. 
     Also in Embodiment 3, in the same manner as Embodiment 1, the second mesh pattern MP 2  is arranged so as to be deviated by ¼ of the first mesh pitch PA 1  with respect to the first mesh pattern MP 1 . Accordingly, in the region R 0  in the electrode intersection portion, in a case where the first electrodes  51  and the second electrodes  61  are observed on the viewing side, as illustrated in  FIG. 19 , the first detection electrode portions  51 A of the first electrodes  51  and the dummy pattern portions  51 B in the first electrode, and the second detection electrode portions  61 A of the second electrodes  61  and the dummy pattern portions  61 B in the second electrode are combined with each other, so as to form the third mesh pattern MP 3  using the rhombic third mesh cell C 3  as constitutional units and having the third mesh pitch PA 3 , in the same manner as in Embodiment 1. The third mesh pitch PA 3  has a value of ¼ of the first mesh pitch PA 1  and the second mesh pitch PA 2  of the first mesh pattern MP 1  and the second mesh pattern MP 2 . 
     In the same manner, even in a case where the dummy pattern portions  51 B in the first electrode that have the fifth dummy unit pattern TSB illustrated in  FIG. 16  are arranged inside the first mesh cells C 1  of the first mesh pattern MP 1 , and the dummy pattern portions  61 B in the second electrode that have the sixth dummy unit pattern T 6 B illustrated in  FIG. 18  are arranged inside the second mesh cell C 2  of the second mesh pattern MP 2 , the third mesh pattern MP 3  having the third mesh pitch PA 3  can be formed. 
     Therefore, the first mesh pitch PA 1  of the first mesh pattern MP 1  that is formed by the first detection electrode portions  51 A of the first electrodes  51  that is used for the detection of a touch operation and the second mesh pitch PA 2  of the second mesh pattern MP 2  that is formed by the second detection electrode portions  61 A of the second electrodes  61  can be set to be four times of the size of the third mesh pitch PA 3  of the third mesh pattern MP 3 . 
     Accordingly, in the same manner as in Embodiment 1, the presence of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B become invisible in a case of being observed on the viewing side, the sizes and the angles of the third mesh cell C 3  can be selected such that the generation of the moire is decreased in a case where the display device is used by being combined with the touch panel  2 , so as to design the third mesh pattern MP 3 , and thus the parasitic capacitances of the first detection electrode portions  51 A and the second detection electrode portions  61 A can be reduced. Therefore, even in a case where a detection electrode portion with a large mesh pattern having a wide pitch which has less parasitic capacitance and high detection sensitivity is used, the visibility is improved, and also in a case where the touch panel  2  and the display device are combined with each other to be used, the generation of the moire can be suppressed.

       FIG. 21  illustrates a partial plan view of a second electrode  81  and a second dummy electrode  82  in an electrode intersection portion of a conductive member according to Embodiment 4 seen from a viewing side. The second electrode  81  and the second dummy electrodes  82  are formed on the second surface  5 B of the transparent insulating substrate  5  illustrated in  FIG. 1 . The second electrode  81  is arranged in a region R 2 A formed along the second direction D 2 , and the second dummy electrode  82  is arranged in a region R 2 B adjacent to the region R 2 A. That is, the second dummy electrode  82  is arranged between the second electrodes  81  adjacent to each other.

     The second dummy electrode  82  has the same configuration as that of the first electrode  81 , but is a floating electrode, and does not function as a sensor in the touch panel  2 . 
     In the same manner as the first mesh pattern MP 1 , the second detection electrode portions  81 A form the second mesh pattern MP 2  having the second mesh pitch PA 2  by using the rhombic second mesh cells C 2  as constitutional units and electrically connecting the plurality of second mesh cells C 2 .

The second electrode  81  has a portion in which the metal fine wire M 2 A and the metal fine wire M 2 B are spaced from each other by a second gap G 2 B that is longer than the first gap G 2 A. 
     The seventh dummy unit pattern T 7 B used in Embodiment 4 has a pattern shape different from the first dummy unit pattern T 1 B in Embodiment 1 as illustrated in  FIG. 4 . As illustrated in  FIG. 20 , the seventh dummy unit pattern  17 B is a pattern in which the metal fine wires M 1 B that do not include a metal fine wire do not intersect with each other in a cross shape and do not completely cross with each other, and has disconnected portions B 1  in which the metal fine wires M 1 B are disconnected. The length of the disconnected portion B 1  is 0.5 μm to 30 μm and preferably 5 μm to 20 μm. 
     In the first mesh cell C 1 , projection portions J 1  projecting from one sides of the first mesh cells C 1  are formed so as to abut end portions of the metal fine wires M 1 B that form the dummy pattern portions  71 B in the first electrode. The end portions of the metal fine wires M 1 B and the end portions of the projection portion J 1  are spaced from each other by the first gap G 1 A. The first electrode  71  has a portion in which the metal fine wire M 1 A and the metal fine wire M 1 B are spaced from each other by the second gap G 1 B that is longer than the first gap G 1 A. In view of reducing the parasitic capacitance of the electrode, the length of the projection portion J 1  is preferably 50 μm or less and particularly preferably 10 μm to 30 μm. Otherwise, the length of the projection portion J 1  is preferably 1/10 or less of a length of one side of the first mesh cell C 1  and more preferably 1/100 to 1/20. 
     In the same manner as in the seventh dummy unit pattern T 7 B, the eighth dummy unit pattern T 8 B used in Embodiment 4 is a pattern in which the metal fine wires M 2 B that do not include a metal fine wire do not intersect with each other in a cross shape and do not completely cross with each other, and has the disconnected portions B 2  in which the metal fine wires M 2 B are disconnected. The length of the disconnected portion B 2  is 0.5 μm to 30 μm and preferably 5 μm to 20 μm. 
     In the second mesh cell C 2 , projection portions J 2  projecting from one sides of the second mesh cells C 2  are formed so as to abut end portions of the metal fine wires M 2 B that form the dummy pattern portions  81 B in the second electrode. The end portions of the metal fine wires M 2 B and the end portions of the projection portion J 2  are spaced from each other by the first gap G 2 A. In view of reducing the parasitic capacitance of the electrode, the length of the projection portion J 2  is preferably 50 μm or less and particularly preferably 10 μm to 30 μm. Otherwise, the length of the projection portion J 2  is preferably 1/10 or less of a length of one side of the second mesh cell C 2  and more preferably 1/100 to 1/20. 
     Also in Embodiment 4, in the same manner as Embodiment 1, the second mesh pattern MP 2  is arranged so as to be deviated by ¼ of the first mesh pitch PA 1  with respect to the first mesh pattern MP 1 . Accordingly, in the electrode intersection portion, in a case where the first electrodes  71  and the second electrodes  81  are observed on the viewing side, as illustrated in  FIG. 22 , the first detection electrode portions  71 A of the first electrodes  71  and the dummy pattern portions  71 B in the first electrode, and the second detection electrode portions  81 A of the second electrodes  81  and the dummy pattern portions  81 B in the second electrode are combined with each other, so as to form the third mesh pattern MP 3  using the rhombic third mesh cell C 3  as constitutional units and having the third mesh pitch PA 3 , in the same manner as in Embodiment 1. The third mesh pitch PA 3  has a value of ¼ of the first mesh pitch PA 1  and the second mesh pitch PA 2  of the first mesh pattern MP 1  and the second mesh pattern MP 2 . 
     In the same manner, even in a case where the dummy pattern portions  71 B in the first electrode that have the seventh dummy unit pattern T 7 B illustrated in  FIG. 20  are arranged inside the first mesh cells C 1  of the first mesh pattern MP 1 , and the dummy pattern portions  81 B in the second electrode that have the eighth dummy unit pattern T 8 B illustrated in  FIG. 21  are arranged inside the second mesh cell C 2  of the second mesh pattern MP 2 , the third mesh pattern MP 3  having the third mesh pitch PA 3  can be formed. 
     Therefore, the first mesh pitch PA 1  of the first mesh pattern MP 1  that is formed by the first detection electrode portions  71 A of the first electrodes  71  that is used for the detection of a touch operation and the second mesh pitch PA 2  of the second mesh pattern MP 2  that is formed by the second detection electrode portions  81 A of the second electrodes  81  can be set to be four times of the size of the third mesh pitch PA 3  of the third mesh pattern MP 3 . 
     Accordingly, in the same manner as in Embodiment 1, the presence of the metal fine wires M 1 A, M 1 B, M 2 A, and M 2 B become invisible in a case of being observed on the viewing side, the sizes and the angles of the third mesh cell C 3  can be selected such that the generation of the moire is decreased in a case where the display device is used by being combined with the touch panel  2 , so as to design the third mesh pattern MP 3 , and thus the parasitic capacitances of the first detection electrode portions  71 A and the second detection electrode portions  81 A can be reduced. Therefore, even in a case where a detection electrode portion with a large mesh pattern having a wide pitch which has less parasitic capacitance and high detection sensitivity is used, the visibility is improved, and also in a case where the touch panel  2  and the display device are combined with each other to be used, the generation of the moire can be suppressed.

     The manufactured conductive member was bonded to a tempered glass having a thickness of 1.1 mm as a cover panel as a cover panel, by using an optical transparent pressures sensitive adhesive sheet having a thickness of 75 μm of 8146-4 (model number) manufactured by The 3M Company, so as to manufacture a touch panel having the structure illustrated in  FIG. 1 . 
     &lt;Touch Sensitivity Evaluation&gt; 
     A front end section of a touch pen in which an outer diameter of the front end section was 1.0 mm was brought in contact with the manufactured touch panel so as to perform the sensitivity evaluation of the touch panel. At this point, based on the position detection accuracy with respect to the contact position between the surface of the touch panel and the front end section of the touch pen, evaluation standards of A to C were determined as follows. In a case where the evaluation was A or B, it is determined that detection accuracy was not problematic in practical use. 
     A: The position detection accuracy was less than 1.0 mm, and correct position detection was able to be made. 
     B: The position detection accuracy was 1.0 mm or more and less than 2.0 mm, there was no problem in practical use. 
     C: The position detection accuracy was 2.0 mm or more, correct position detection was not able to be made. 
     &lt;Visibility Evaluation&gt; 
     The manufactured touch panel was observed with bare eyes of 10 observers at a position spaced by 5 cm from the front surface of the touch panel so as to evaluate whether metal fine wires were recognized. With respect to the visibility, the evaluation standards of A to C were determined as follows, the most frequent evaluation result among the evaluation results of 10 observers was set as a final evaluation result with respect to the touch panel. In a case where the evaluation was A or B, it is determined that visibility was not problematic in practical use. 
     A: The metal fine wire was not recognized at all. 
     B: The metal fine wire was slightly recognized, but was not problematic in practical use. 
     C: The metal fine wire was clearly recognized. 
     &lt;Moire Evaluation&gt; 
     The image displayed in a state in which the manufactured touch panel was arranged on the liquid crystal display module and the liquid crystal display module performed image display on the entire surface was observed with the bare eyes of 10 observers, so as to evaluate whether the moire generated on the displayed image was recognized. With respect to the generation of the moire, the evaluation standards of A to C were determined as follows, the most frequent evaluation result among the evaluation results of 10 observers was set as a final evaluation result with respect to the touch panel. In a case where the evaluation was A or B, it is determined that the moire was not problematic in practical use. 
     A: The moire was not recognized. 
     B: The moire was slightly recognized, but was not problematic in practical use. 
     C: The moire was noticeable. 
     Here, the method of manufacturing the conductive member is specifically described.

     Thereafter, washing with water was performed by a flocculation method according to a general method. Specifically, the temperature was decreased to 35° C., 3 liters of distilled water was added, and sulfuric acid was used to lower the pH until the silver halide was precipitated (in the range of pH 3.6±0.2). Next, about 3 liters of the supernatant was removed (first washing with water). Additional 3 liters of distilled water was added, and sulfuric acid was added, until the silver halide had precipitated. Again, 3 liters of the supernatant was removed (second washing with water). The same operation as the second washing with water was further repeated one more time (third washing with water) to complete a water washing-desalting step. The emulsion after washing and desalting was adjusted to pH 6.4 and pAg 7.5, 3.9 g of gelatin, 10 mg of sodium benzenethiosulfonate, 3 mg of sodium benzenethiosulfinate, 15 mg of sodium thiosulfate, and 10 mg of chloroauric acid were added, chemical sensitization was performed so as to obtain the optimum sensitivity at 55° C., and 100 mg of 1,3,3a,7-tetraazaindene as a stabilizer and 100 mg of PROXEL (trade name, manufactured by ICI Co., Ltd.) as a preservative were added. The finally obtained emulsion was a silver iodochlorobromide cubic grain emulsion including 0.08 mol % of silver iodide, having a proportion of silver chlorobromidea of 70 mol % of silver chloride and 30 mol % of silver bromide, and having an average particle diameter of 0.22 μm and a coefficient of variation of 9%. 
     (Preparation of Composition for Forming Photosensitive Layer) 
     1.2×10 −4  mol/mol Ag of 1,3,3a,7-tetraazaindene, 1.2×10 −2  mol/mol Ag of hydroquinone, 3.0×10 −4  mol/mol Ag of citric acid, 0.90 g/mol Ag of 2,4-dichloro-6-hydroxy-1,3,5-triazine sodium salt, and a slight amount of a hardener were added to the above emulsion, and pH of the coating solution was adjusted to 5.6 by using citric acid. 
     A polymer latex containing a polymer represented by (P-1) and dialkylphenyl PEO sulfate ester as a dispersing agent with respect to gelatin contained in the above coating solution (a mass ratio of dispersing agent/polymer was 2.0/100=0.02) was added such that polymer/gelatin (mass ratio)=0.5/1 was satisfied. 
     
       
         
         
             
             
         
       
     
     EPOXY RESIN DY 022 (trade name, manufactured by Nagase ChemteX Corp.) was added as a crosslinking agent. The addition amount of the crosslinking agent was adjusted such that the amount of the crosslinking agent in the photosensitive layer described below was 0.09 g/m 2 . 
     The composition for forming a photosensitive layer was prepared as above. 
     The polymer represented by (P-1) described above was synthesized with reference to JP3305459B and JP3754745B. 
     (Photosensitive Layer Formation Step) 
     Both sides of the transparent insulating substrate were coated with the above polymer latex, so as to provide an undercoat layer having a thickness of 0.05 μm. As the transparent insulating substrate, polyethylene terephthalate film of 38 μm (manufactured by Fujifilm Corporation) was used. 
     Next, an antihalation layer was formed of a mixture of the above polymer latex, gelatin, and a dye having an optical density of about 1.0 and being decolorized by alkali of a developer was provided on the undercoat layer. The mixing mass ratio (polymer/gelatin) of the polymer and the gelatin in the antihalation layer was 2/1, and the content of the polymer was 0.65 g/m 2 . 
     The antihalation layer was coated with the composition for forming a photosensitive layer and was further coated with a composition obtained by mixing the polymer latex, gelatin, EPOCROSS K-2020E (trade name, manufactured by Nippon Shokubai Co., Ltd., oxazoline-based crosslinking reactive polymer latex) (crosslinkable group, oxazoline group)), and SNOWTEX C (registered trademark, trade name, manufactured by Nissan Chemical Industries, Ltd., colloidal silica) by a solid content mass ratio (polymer/gelatin/EPOCROSS K-2020E/SNOWTEX C (registered trademark)) of 1/1/0.3/2 such that the amount of gelatin was 0.08 g/m 2 , so as to obtain a support of which photosensitive layers were formed on both sides. A support having photosensitive layers formed on both sides is referred to as a film A. The formed photosensitive layer had a silver content of 6.2 g/m 2  and a gelatin content of 1.0 g/m 2 . 
     (Exposure and Development Step) 
     For example, a first photo mask for forming a first electrode having a pattern as illustrated in  FIG. 3  and a second photo mask for forming a second electrode having a pattern as illustrated in  FIG. 6  were respectively formed, the first photo mask and the second photo mask were arranged on both sides of the film A, and the both sides were simultaneously exposed with parallel light by using a high pressure mercury lamp as a light source. 
     After the exposure, development was performed by using the following developer, and development was performed by using a fixing solution (trade name, N3X-R for CN16X, manufactured by Fujifilm Corporation). Rinsing with pure water was performed, and the water was dried, so as to obtain a support in which metal fine wires made of Ag (silver) and gelatin layers were formed on both surfaces. The gelatin layer was formed between the metal wires. The obtained film was referred to as a film B. 
     (Composition of Developer) 
     The following compounds were contained in 1 liter (L) of the developer. 
     Hydroquinone . . . 0.037 mol/L 
     N-methylaminophenol . . . 0.016 mol/L 
     Sodium metaborate . . . 0.140 mol/L 
     Sodium hydroxide . . . 0.360 mol/L 
     Sodium bromide . . . 0.031 mol/L 
     Potassium metabisulfite . . . 0.187 mol/L 
     (Gelatin Degradation Treatment) 
     The film B was immersed in an aqueous solution (concentration of proteolytic enzyme: 0.5 mass %, solution temperature: 40° C.) of a proteolytic enzyme (BIOPLASE AL-15FG manufactured by Nagase ChemteX Corp.) in an aqueous solution for 120 seconds. The film B was extracted from the aqueous solution, immersed in warm water (solution temperature: 50° C.) for 120 seconds, and washed. The film after gelatin degradation treatment is referred to as a film C. 
     &lt;Resistance Reduction Treatment&gt; 
     A calender treatment was performed on the film C by using a calender device equipped with metal rollers at a pressure of 30 kN. At this point, two polyethylene terephthalate films having a rough surface shape of line roughness Ra=0.2 μm, Sm=1.9 μm (measured with a shape analysis laser microscope VK-X110 manufactured by Keyence Corporation (JIS-B-0601-1994)) were transported such that the rough surfaces face the front and back surfaces of the film C, and the rough shapes were transferred and formed on the front and back surfaces of the film C. 
     After the calender treatment, the film C was passed through an overheated steam tank at a temperature of 150° C. for 120 seconds to perform heat treatment. The film after the heat treatment is referred to as a film D. This film D was a conductive member.

     In Comparative Example 1, the second mesh pattern MP 2  is arranged so as to be deviated by ½ of the first mesh pitch PA 1  with respect to the first mesh pattern MP 1 . Accordingly, in the region R 0  in the electrode intersection portion, in a case where the first electrodes  91  and the second electrodes  92  are observed on the viewing side, as illustrated in  FIG. 25 , the first detection electrode portions  91 A of the first electrodes  91  and the second detection electrode portions  92 A of the second electrode  92  are combined with each other, so as to form the fourth mesh pattern MP 4  using the rhombic fourth mesh cell C 4  as constitutional units and having the fourth mesh pitch PA 4 . The fourth mesh pitch PA 4  has a value of ½ of the first mesh pitch PA 1  and the second mesh pitch PA 2  of the first mesh pattern MP 1  and the second mesh pattern MP 2 .

     As presented in Table 1, in Examples 1 to 4, all of the sensitivity evaluation, the visibility evaluation, and the moire evaluation were “A” or “B”, and the detection sensitivity was improved, the visibility was excellent, and the generation of the moire can be decreased. Particularly, in Examples 1 and 4, all of the sensitivity evaluation, the visibility evaluation, and the moire evaluation were “A”, the detection sensitivity was excellent, the visibility was improved, and the generation of the moire was decreased. 
     Meanwhile, in Comparative Example 1, the sensitivity evaluation was “A”, but the visibility evaluation and the moire evaluation were “C”. In Comparative Example 2, the visibility evaluation and the moire evaluation were “A”, but the sensitivity evaluation was “C”. In this manner, in Comparative Examples 1 and 2, all of the sensitivity, the visibility, and the moire were not highly evaluated. 
     In Example 3, since, according to the presence of the dummy pattern portions  51 B in the first electrode, four cells having a half pitch of the first mesh pitch PA 1  were formed in the first mesh cells C 1  of the first mesh pattern MP 1  of the first detection electrode portions  51 A, and in the same manner, according to the presence of the dummy pattern portions  61 B in the second electrode, four cells having a half pitch of the second mesh pitch PA 2  were formed in the second mesh cell C 2  of the second mesh pattern MP 2  of the second detection electrode portions  61 A, the parasitic capacitances of the first detection electrode portions  51 A and the second detection electrode portions  61 A were increased compared with those in Examples 1 and 2, and thus the sensitivity evaluation was “B”. 
     In Examples 2 and 3 having points at which the dummy pattern portions in the second electrode intersected with each other in a cross shape, the visibility evaluation and the moire evaluation were “B”, but this is because points at which the dummy pattern portions in the second electrode intersected with each other in a cross shape were formed larger than the design value due to diffracted light from the photo mask edge portion in the exposure and development step in a case of manufacturing the conductive member. 
     In Comparative Example 1, it is considered that, since all of the first electrode  91  and the second electrode  92  have the first mesh pitch PA 1 , the sensitivity evaluation was “A”, but the mesh pitch (fourth mesh pitch PA 4 ) of the fourth mesh pattern MP 4  formed by overlapping the first electrodes  91  and the second electrodes  92  with each other was twice the mesh pitch (the third mesh pitch PA 3 ) of the third mesh pattern MP 3  in Examples 1 to 3, that is, the mesh pitch was wide, the visibility evaluation and the moire evaluation were “C”. 
     It is considered that Comparative Example 2 did not have a dummy pattern portion in the electrode, but since the first electrodes  101  and the second electrodes  102  were overlapped with each other, the third mesh pattern MP 3  having the third mesh pitch PA 3  was formed as in Example 1, and thus the visibility evaluation and the moire evaluation were “A”. Meanwhile, it is considered that, since the fifth mesh pattern MP 5  formed of the first detection electrode portion  101 A of the first electrode  101  used for detecting a touch operation and the sixth mesh pattern MP 6  formed by the second detection electrode portion  102 A of the second electrode  102  had a half pitch (fourth mesh pitch PA 4 ) of the first mesh pitch PA 1  in Example 1, the parasitic capacitance of the first detection electrode portion  101 A and the second detection electrode portion  102 A were increased, and thus the sensitivity evaluation was “C”. 
     Another aspect is noted as follows. 
     A conductive member comprising: 
     a plurality of first electrodes each of which extend in a first direction and which are arranged in juxtaposition in a second direction orthogonal to the first direction; and 
     a plurality of second electrodes each of which extend in the second direction and which are arranged in juxtaposition in the first direction, 
     wherein the plurality of first electrodes and the second electrodes are arranged to face each other in an insulation state, 
     the first electrode has a first detection electrode portion having a first mesh pattern constituted by electrically connecting a plurality of first mesh cells formed of metal fine wires and a dummy pattern portion in a first electrode which is formed of metal fine wires arranged inside the first mesh cell of the first mesh pattern so as to be insulated from the first detection electrode portion, 
     the second electrode has a second detection electrode portion having a second mesh pattern constituted by electrically connecting a plurality of second mesh cells formed of metal fine wires and a dummy pattern portion in the second electrode which is formed of metal fine wires arranged inside the second mesh cell of the second mesh pattern so as to be insulated from the second detection electrode portion, and 
     in a region in which the first electrode and the second electrode are overlapped with each other, a third mesh pattern is constituted by a plurality of third mesh cells formed by combining the first detection electrode portion, the dummy pattern portion in the first electrode, the second detection electrode portion, and the dummy pattern portion in the second electrode.
