       FIG. 1  is a plan view illustrating a touch sensor  10  in one or more embodiments of the present invention, and  FIG. 2  is an exploded perspective view illustrating the touch sensor  10  according to one or more embodiments. The touch sensor  10  illustrated in  FIG. 1  and  FIG. 2  is a projection electrostatic capacitance type touch panel sensor, and for example, is used as an input device having a function of detecting a touch position by being combined with a display device (not illustrated) or the like. The display device is not particularly limited, but a liquid crystal display, an organic EL display, electronic paper or the like can be used. The touch sensor  10  includes a detection electrode and a driving electrode disposed to face each other (an electrode  22 A and an electrode  32 A described below), and a predetermined voltage is periodically applied between two electrodes from an external circuit (not illustrated) through a connection wiring body  50 . 
     In such a touch sensor  10 , for example, in a case where a finger of an operator (an external conductor) is close to the touch sensor  10 , a capacitor (electrostatic capacitance) is formed between the external conductor and the touch sensor  10 , and an electrical state between two electrodes is changed. The touch sensor  10  is capable of detecting an operating position of the operator on the basis of an electrical change between two electrodes. 
     As illustrated in  FIG. 1  and  FIG. 2 , the touch sensor  10  includes a wiring body assembly  11  and a cover panel  70 . The wiring body assembly  11  includes a first wiring body  20 , a second wiring body  30  which is disposed on the first wiring body  20 , a coating resin layer  40  which is disposed on the second wiring body  30 , and a connection wiring body  50 . The first wiring body  20 , the second wiring body  30  and the coating resin layer  40  are configured to have transparency (light transmittance) as a whole in order to ensure visibility of the display device. 
     The first wiring body  20  includes a first support resin layer  21  which is formed in a rectangular shape, and a plurality of electrodes  22 A for detection, a plurality of lead-out wires  22 B and a plurality of terminal portions  22 C which are formed on an upper surface of the first support resin layer  21 . 
     The first support resin layer  21  is made of a resin material having transparency. For example, an UV curable resin, a thermosetting resin, a thermoplastic resin and the like such as an epoxy resin, an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, a silicone resin, a phenolic resin and a polyimide resin can be exemplified as the resin material having transparency.

The binder resin may be omitted from the material configuring the electrode  22 A, the lead-out wire  22 B and the terminal portion  22 C. 
     The number of electrodes  22 A of the first wiring body  20  is not particularly limited, and can be arbitrarily set. The number of lead-out wires  22 B and the number of terminal portions  22 C of the first wiring body  20  are set according to the number of electrodes  22 A.

     The second support resin layer  31  is made of a resin material having transparency. For example, an UV curable resin, a thermosetting resin, a thermoplastic resin and the like such as an epoxy resin, an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, a silicone resin, a phenolic resin and a polyimide resin can be exemplified as the resin material having transparency. 
     The electrode  32 A is in a reticular shape. Each of the electrodes  32 A extends in the Y direction of the drawing, and the plurality of electrodes  32 A are parallel in the X direction of the drawing. One end of each of the lead-out wires  32 B is connected to one longitudinal direction end of each of the electrodes  32 A. Each of the lead-out wires  32 B extends from the one longitudinal direction end of each of the electrodes  32 A to the connection portion with respect to the connection wiring body  50 . Each of the terminal portions  32 C is disposed on the other end of each of the lead-out wires  32 B, and the terminal portion  32 C is electrically connected to the connection wiring body  50 . 
     The electrode  32 A, the lead-out wire  32 B and the terminal portion  32 C are made of a conductive material (conductive particles) and a binder resin. A metal material such as silver, copper, nickel, tin, bismuth, zinc, indium and palladium, and a carbon-based material such as graphite, carbon black (furnace black, acetylene black, ketchen black), a carbon nanotube and a carbon nanofiber can be exemplified as the conductive material.

An acrylic resin, a polyester resin, an epoxy resin, a vinyl resin, a urethane resin, a phenolic resin, a polyimide resin, a silicone resin, a fluorine resin and the like can be exemplified as the binder resin. The electrode  32 A, the lead-out wire  32 B and the terminal portion  32 C are formed by being coated with a conductive paste and by curing the conductive paste. A conductive paste which is obtained by mixing the conductive material and the binder resin described above, with water or a solvent, and various additives, can be exemplified as a specific example of the conductive paste. α-Terpineol, butyl carbitol acetate, butyl carbitol, 1-decanol, butyl cellosolve, diethylene glycol monoethyl ether acetate, tetradecane and the like can be exemplified as the solvent contained in the conductive paste. The binder resin may be omitted from the material configuring the electrode  32 A, the lead-out wire  32 B and the terminal portion  32 C. 
     The number of electrodes  32 A of the second wiring body  30  is not particularly limited, and can be arbitrarily set. The number of lead-out wires  32 B and the number of terminal portions  32 C of the second wiring body  30  are set according to the number of electrodes  32 A. 
     The coating resin layer  40  is formed in a rectangular shape, the coating resin layer  40  is formed to cover the upper surface of the second support resin layer  31 , the electrode  32 A and the lead-out wire  32 B of the second wiring body  30 . Here, a rectangular cut-out portion  40 A is formed on one side of the coating resin layer  40 , a part of the second wiring body  30  including the connection portion with respect to the connection wiring body  50  is exposed from the second support resin layer  31  through the cut-out portion  40 A, and a portion which is exposed is the terminal portion  32 C. A part of the first wiring body  20  including the connection portion with respect to the connection wiring body  50  is also exposed from the coating resin layer  40  through the cut-out portion  40 A. 
     The coating resin layer  40  is made of a resin material having transparency. For example, an UV curable resin, a thermosetting resin, a thermoplastic resin and the like such as an epoxy resin, an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, a silicone resin, a phenolic resin and a polyimide resin can be exemplified as the resin material having transparency. The coating resin layer  40  may be a multi-layer. In one or more embodiments, the first layer positioned on the second wiring body  30  side may be formed of the UV curable resin, the thermosetting resin, the thermoplastic resin and the like such as the epoxy resin, the acrylic resin, the polyester resin, the urethane resin, the vinyl resin, the silicone resin, the phenolic resin and the polyimide resin described above, and the second layer positioned on a side opposite to the second wiring body  30  (the cover panel  70  side) may be an adhesive layer by using a known adhesive agent such as a silicon resin-based adhesive agent, an acrylic resin-based adhesive agent, a urethane resin-based adhesive agent and a polyester resin-based adhesive agent. 
     The cover panel  70  adheres to an upper surface of the coating resin layer  40  through a transparent adhesive layer  60  (refer to  FIG. 4  and  FIG. 5 ). The transparent adhesive layer  60  is an optical transparent adhesive film, and can be formed by using a known adhesive agent such as a silicon resin-based adhesive agent, an acrylic resin-based adhesive agent, a urethane resin-based adhesive agent and a polyester resin-based adhesive agent. Here, in one or more embodiments, the transparent adhesive layer  60  is formed on a lower surface of the cover panel  70  in advance, but in a case where the coating resin layer  40  has a multi-layered structure and a layer of the coating resin layer  40  on the cover panel  70  side is an adhesive layer, it is not necessary to form the transparent adhesive layer  60 , and thus, the transparent adhesive layer  60  may be omitted. In one or more embodiments, the transparent adhesive layer  60  is formed on the lower surface of the cover panel  70  in advance, and thus, the transparent adhesive layer  60  exists on the cut-out portions  31 A and  40 A. However, in a case where the coating resin layer  40  has a multi-layered structure and the layer of the coating resin layer  40  on the cover panel  70  side is an adhesive layer, the adhesive layer may not exist on the cut-out portions  31 A and  40 A. 
     The cover panel  70  includes: a transparent portion  71  which is capable of transmitting a visible light ray; and a shielding portion  72  which shields a visible light ray. The transparent portion  71  is formed in a rectangular shape, and the shielding portion  72  is formed around the transparent portion  71  in the shape of a rectangular frame. For example, a glass material such as soda lime glass and borosilicate glass, and a resin material such as polymethyl methacrylate (PMMA) and polycarbonate (PC) can be exemplified as a transparent material configuring the cover panel  70 . The shielding portion  72  is formed in an outer circumference portion on a rear surface of the cover panel  70 , for example, by being coated a black ink. 
     The connection wiring body  50  is an FPC and includes a strip-like substrate (base material)  51 , and a plurality of wirings  52  and a plurality of wirings  53  which are formed on a lower surface of the substrate  51 . The substrate  51  can be configured of a film material made of, for example, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), a polyimide resin (PI), a polyether imide resin (PEI) and the like. 
     A slit  51 C is formed in a central portion in a width direction of one longitudinal direction end of the substrate  51 , and the one longitudinal direction end of the substrate  51  is divided by the slit  51 C in the width direction. One end of the plurality of wirings  52  is disposed on a lower surface on one side (a first branch portion  51 A) of the one longitudinal direction end of the substrate  51 , and one end of the plurality of wirings  53  is disposed on a lower surface on the other side (a second branch portion  51 B) of the one longitudinal direction end of the substrate  51 . 
     The plurality of wirings  52  are disposed corresponding to the plurality of lead-out wires  22 B of the first wiring body  20 . The plurality of wirings  52  are parallel to each other. A terminal portion  52 C corresponding to the terminal portion  22 C of the lead-out wire  22 B is disposed on one end of each of the wirings  52 . 
     The plurality of wirings  53  is disposed corresponding to the plurality of lead-out wires  32 B of the second wiring body  30 . The plurality of wirings  53  are parallel to each other. A terminal portion  53 C corresponding to the terminal portion  32 C of the lead-out wire  32 B is disposed on one end of each of the wirings  53 . A material configuring the wirings  52  and  53  is not particularly limited, and the same material as the material of the lead-out wires  22 B and  32 B may be used. 
     The connection wiring body  50  is not limited to the FPC, and for example, may be the other wiring board such as a rigid substrate or a rigid flexible substrate. 
       FIG. 3  is an enlarged plan view illustrating a connection portion between the touch sensor  10  and the connection wiring body  50  according to one or more embodiments,  FIG. 4  is a cross-sectional view along line IV-IV of  FIG. 3 , and  FIG. 5  is a cross-sectional view along line V-V of  FIG. 3 . As illustrated in  FIG. 3  and  FIG. 4 , an adhesive portion  51 D of the first branch portion  51 A on a tip end side and a region of the first support resin layer  21  in the cut-out portion  31 A vertically face each other through the conductive adhesive layer  80 , and adhere to each other with the conductive adhesive layer  80 . The terminal portion  52 C of the wiring  52  and the terminal portion  22 C of the lead-out wire  22 B vertically face each other through the conductive adhesive layer  80 . 
     The conductive adhesive layer  80  has a function of electrically and mechanically connecting the terminal portion  52 C and the terminal portion  22 C to each other. In addition, the conductive adhesive layer  80  has a function of insulating the terminals adjacent to each other. An anisotropic conductive film (ACF), an anisotropic conductive paste (ACP) and the like can be exemplified as such a conductive adhesive layer  80 . 
     The terminal portion  52 C and the terminal portion  22 C may be electrically and mechanically connected to each other with using a metal paste such as a silver paste or a solder paste, without using the anisotropic conductive material. In one or more embodiments, it is necessary to form a plurality of adhesive layers with an interval such that the adjacent terminals are insulated. 
     The second support resin layer  31  is formed with an interval with respect to the adhesive portion  51 D of the first branch portion  51 A. Accordingly, through the cut-out portion  31 A, the upper surface of the first support resin layer  21  and the terminal portion  22 C of the first wiring body  20  are exposed from the first branch portion  51 A, the conductive adhesive layer  80  and the second support resin layer  31 . 
     A height H4 from the upper surface of the first support resin layer  21  to the upper surface of the second support resin layer  31  is comparatively higher than a height H2 from the upper surface of the first support resin layer  21  to an upper surface of the adhesive portion  51 D of the first branch portion  51 A. It is not essential that the height H4 is comparatively higher than the height H2 as long as a height H0 from the upper surface of the first support resin layer  21  to an upper surface of the transparent adhesive layer  60  and a height H3 from the upper surface of the first support resin layer  21  to the upper surface of the coating resin layer  40  satisfy a relationship of Expression (2′) described below and Expression (2) described below. 
     A convex portion  82  is formed on the upper surface of the first support resin layer  21  along a tip end  51 E of the first branch portion  51 A from one end to the other end of the tip end  51 E. The convex portion  82  is integrally formed with the conductive adhesive layer  80  by the conductive adhesive material of which the conductive adhesive layer  80  is made. 
     The convex portion  82  protrudes from the upper surface of the first support resin layer  21  so as to be in contact with the tip end  51 E of the first branch portion  51 A. In one or more embodiments, a height H1 from the upper surface of the first support resin layer  21  to a distal end of the convex portion  82  and the height H2 from the upper surface of the first support resin layer  21  to the upper surface of the adhesive portion  51 D of the first branch portion  51 A satisfy a relationship of Expression (1) described below. 
       H1&gt;H2  (1)
 
     In one or more embodiments, the height H0 from the upper surface of the first support resin layer  21  to the upper surface of the transparent adhesive layer  60  and the height H1 from the upper surface of the first support resin layer  21  to the distal end of the convex portion  82  satisfy a relationship of Expression (2′) described below, thereby the convex portion  82  is not in contact with the cover panel  70 . In one or more embodiments, the height H1 and the height H3 from the upper surface of the first support resin layer  21  to the upper surface of the coating resin layer  40  satisfy a relationship of Expression (2) described below. 
       H0≥H1  (2′)
 
       H3≥H1  (2)
 
     The convex portion  82  is formed to extend in parallel with a wall surface  31 B of the second support resin layer  31  (a depth direction of a paper surface of  FIG. 4 , and a direction parallel to an extending direction of the tip end  51 E), and a groove  86  is formed by the convex portion  82 , the wall surface  31 B and the upper surface of the first support resin layer  21 . The groove  86  is filled with a sealing resin  90 , and an exposed portion of the terminal portion  22 C which is exposed from the first branch portion  51 A, the conductive adhesive layer  80 , the convex portion  82  and the second support resin layer  31  is sealed with the sealing resin  90 . Accordingly, the entire terminal portion  22 C of the first wiring body  20  is coated with a resin, and thus, a defect due to the exposure does not occur in the terminal portion  22 C of the first wiring body  20 . Here, in a case where the conductive adhesive layer  80  is formed by curing a liquid conductive adhesive agent, the convex portion  82  which is in contact with the end portion of the substrate  51  and defines the groove  86  together with the upper surface of the first support resin layer  21  and the wall surface  31 B of the second support resin layer  31  is not formed. In contrast, in one or more embodiments, the conductive adhesive layer  80  is formed by using an anisotropic conductive film or an anisotropic conductive paste of which a viscosity is adjusted, and thus, the convex portion  82  can be formed so as to be in contact with the end portion of the substrate  51  and to define the groove  86  together with the upper surface of the first support resin layer  21  and the wall surface  31 B of the second support resin layer  31 . 
     The sealing resin  90  extends from one end to the other end of the groove  86  and has a function of reinforcing a region of the first support resin layer  21  between the convex portion  82  and the wall surface  31 B of the second support resin layer  31 . Accordingly, reliability in a mechanical strength of the terminal portion  22 C and the lead-out wire  22 B is improved. The sealing resin  90  protrudes from both ends of the groove  86  and spreads to both sides of the adhesive portion  51 D in the longitudinal direction. Then, the corner portion  31 C of the cut-out portion  31 A and a corner portion  40 C of the cut-out portion  40 A are also filled with the sealing resin  90 . 
     An UV curable resin, a thermosetting resin, a thermoplastic resin and the like such as an epoxy resin, an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, a silicone resin, a phenolic resin and a polyimide resin can be exemplified as a resin material configuring the sealing resin  90 . 
     As illustrated in  FIG. 3  and  FIG. 5 , an adhesive portion  51 F of the second branch portion  51 B on the tip end side and a region of the coating resin layer  40  in the cut-out portion  40 A vertically face each other through the above-described conductive adhesive layer  80  and adhere to each other with the conductive adhesive layer  80 . The terminal portion  53 C of the wiring  53  and the terminal portion  32 C of the lead-out wire  32 B vertically face each other through the conductive adhesive layer  80  and are electrically and mechanically connected to each other with the conductive adhesive layer  80 . 
     The coating resin layer  40  is formed with an interval with respect to the adhesive portion  51 F of the second branch portion  51 B. Accordingly, the upper surface of the second support resin layer  31  and the terminal portion  32 C of the second wiring body  30  are exposed from the second branch portion  51 B, the conductive adhesive layer  80  and the coating resin layer  40  through the cut-out portion  40 A. 
     A height H8 from the upper surface of the second support resin layer  31  to the upper surface of the coating resin layer  40  is comparatively higher than a height H6 from the upper surface of the second support resin layer  31  to the upper surface of the adhesive portion  51 D of the first branch portion  51 A. It is not essential that the height H8 is comparatively higher than the height H6, as long as a height H7 from the upper surface of the second support resin layer  31  to the upper surface of the transparent adhesive layer  60  and the height H8 from the upper surface of the second support resin layer  31  to the upper surface of the coating resin layer  40  satisfy a relationship of Expression (4) described below and Expression (5) described below. 
     A convex portion  84  is formed on the upper surface of the second support resin layer  31  along a tip end  51 G of the second branch portion  51 B from one end to the other end of the tip end  51 G. The convex portion  84  is integrally formed with the conductive adhesive layer  80  by the conductive adhesive material of which the conductive adhesive layer  80  is made. 
     The convex portion  84  protrudes from the upper surface of the second support resin layer  31  so as to be in contact with the tip end  51 G of the second branch portion  51 B. In one or more embodiments, a height H5 from the upper surface of the second support resin layer  31  to a distal end of the convex portion  84  and the height H6 from the upper surface of the second support resin layer  31  to the upper surface of the adhesive portion  51 F of the second branch portion  51 B satisfy a relationship of Expression (3) described below.

     In one or more embodiments, the height H7 from the upper surface of the second support resin layer  31  to the upper surface of the transparent adhesive layer  60  and the height H5 from the upper surface of the second support resin layer  31  to the distal end of the convex portion  84  satisfy a relationship of Expression (4) described below, thereby the convex portion  84  is not in contact with the cover panel  70 . In one or more embodiments, the height H5 and the height H8 from the upper surface of the second support resin layer  31  to the upper surface of the coating resin layer  40  satisfy a relationship of Expression (5) described below. 
       H7≥H5  (4)
 
       H8≥H5  (5)
 
     The convex portion  84  is formed to extend in parallel with a wall surface  40 B of the coating resin layer  40  (a depth direction of a paper surface of  FIG. 5 , and a direction parallel to an extending direction of the tip end  51 G), and a groove  88  is formed by the convex portion  84 , the wall surface  40 B and the upper surface of the second support resin layer  31 . The groove  88  is filled with the sealing resin  90 , and an exposed portion of the terminal portion  32 C which is exposed from the second branch portion  51 B, the conductive adhesive layer  80 , the convex portion  84  and the coating resin layer  40  is sealed with the sealing resin  90 . Accordingly, the entire terminal portion  32 C of the second wiring body  30  is coated with a resin, and thus, a defect due to the exposure does not occur in the terminal portion  32 C of the second wiring body  30 . Here, in a case where the conductive adhesive layer  80  is formed by curing a liquid conductive adhesive agent, the convex portion  84  which is in contact with the end portion of the substrate  51  and defines the groove  88  together with the upper surface of the second support resin layer  31  and the wall surface  40 B of the coating resin layer  40  is not formed. In contrast, in one or more embodiments, the conductive adhesive layer  80  is formed by using an anisotropic conductive film or an anisotropic conductive paste of which a viscosity is adjusted, and thus, the convex portion  84  can be formed so as to be in contact with the end portion of the substrate  51  and to define the groove  88  together with the upper surface of the second support resin layer  31  and the wall surface  40 B of the coating resin layer  40 . 
     The sealing resin  90  extends from one end to the other end of the groove  88  and has a function of reinforcing a region of the second support resin layer  31  between the convex portion  84  and the wall surface  40 B of the coating resin layer  40 . Accordingly, reliability in a mechanical strength of the terminal portion  32 C and the lead-out wire  32 B is improved. The sealing resin  90  may protrude from both ends of the groove  88  and may spread to both sides of the adhesive portion  51 D in the longitudinal direction. 
     Hereinafter, a connection method between the touch sensor  10  and the connection wiring body  50  will be described. Since a connection method between the first wiring body  20  and the connection wiring body  50  is similar to a connection method between the second wiring body  30  and the connection wiring body  50 , the description of the connection method of the latter will be omitted, and the description of the connection method of the former will be quoted. 
       FIG. 6  and  FIG. 7  are cross-sectional views for illustrating the connection method between the first wiring body  20  and the connection wiring body  50  according to one or more embodiments. As illustrated in  FIG. 6  and  FIG. 7 , the convex portion  82  is formed at the same time of thermo-compression bonding the terminal portion  52 C of the connection wiring body  50  and the terminal portion  22 C of the first wiring body  20  through the conductive adhesive layer  80 . A substrate  12  is disposed on the lower surface of the first support resin layer  21  at the time of manufacturing the touch sensor  10 . 
     First, as illustrated in  FIG. 6 , a conductive adhesive material  81  such as ACF or ACP configuring the conductive adhesive layer  80  is disposed at an adhesive region of the first support resin layer  21 . Here, a width D 1  of the conductive adhesive material  81  is set to be wider than a width D 2  of the adhesive portion  51 D of the first branch portion  51 A. Accordingly, the conductive adhesive material  81  includes: a region  81 A interposed between the adhesive portion  51 D of the first branch portion  51 A and the first support resin layer  21 ; and a region  81 B having a width d and protruding from the adhesive portion  51 D of the first branch portion  51 A 
     A thickness t of the conductive adhesive material  81  is set to be comparatively thicker than a thickness which adhesion of the terminal portion  52 C and the terminal portion  22 C requires. For example, in a case where the thickness of the substrate  51  is 30 μm and the thickness of the wiring  52  is 35 μm, the thickness t of the conductive adhesive material  81  is set to 35 μm. 
     Next, as illustrated in  FIG. 7 , the adhesive portion  51 D of the first branch portion  51 A and the adhesive region of the first support resin layer  21  are thermo-compression bonded with a compression head  1  and a compression base  2  in a state where the conductive adhesive material  81  is interposed between the adhesive portion  51 D of the first branch portion  51 A and the adhesive region of the first support resin layer  21 . Here, at the time of thermo-compression bonding, a thickness of a region  81 A of the conductive adhesive material  81  is reduced, whereas a region  81 B of the conductive adhesive material  81  protrudes so as to be in contact with a side surface of the tip end  51 E of the first branch portion  51 A and the compression head  1 . Accordingly, the convex portion  82  protruding from the upper surface of the first support resin layer  21  to the height H1 of exceeding the upper surface of the adhesive portion  51 D of the first branch portion  51 A is formed. 
       FIG. 8  is a graph illustrating a test result of confirming a relationship between a width d of the region  81 B of the conductive adhesive material  81  and the height H1 of the convex portion  82  according to one or more embodiments. As illustrated in the graph, it is confirmed that the height H1 of the convex portion  82  tends to increase as the width d of the region  81 B of the conductive adhesive material  81  increases. In this confirmation test, an anisotropic conductive film (a thickness of 35 μm) of a model number of CP801CM-35C manufactured by Dexerials Corporation is used, the width and the interval of the terminal portion  52 C are respectively set to 0.2 mm, the thickness of the substrate  51  is set to 30 μm, and the thickness of the terminal portion  52 C is set to 35 μm. 
     The terminal portion  52 C of the connection wiring body  50  and the terminal portion  22 C of the first wiring body  20  are thermo-compression bonded through the conductive adhesive material  81  and the convex portion  82  is formed, and then the sealing resin  90  is formed. In this process, the groove  86  formed by the convex portion  82 , the wall surface  31 B of the second support resin layer  31  and the upper surface of the first support resin layer  21  is filled with a liquid resin, and the liquid resin is cured. In the filling of the liquid resin, the liquid resin is dropped into the groove  86  by using a dispenser, and the dropped liquid resin spreads in the entire groove  86 . 
     Here, the liquid resin at the time of filling tends to wet-spread not only in an extending direction of the sealing resin  90  but also in the width direction. However, since the convex portion  82  exists on one side of the sealing resin  90  in the width direction and the second support resin layer  31  and the coating resin layer  40  exist on the other side, the liquid resin at the time of filling is blocked by the convex portion  82 , the second support resin layer  31  and the coating resin layer  40 , and the wet-spreading of the liquid resin at the time of filling in the width direction is restricted. Accordingly, the liquid resin at the time of filling wet-spreads in the extending direction in a state where the width is constant, and a deposition height in the groove  86  increases. 
       FIG. 10  is an enlarged cross-sectional view illustrating the connection portion between the touch sensor  10  and the connection wiring body  50  in a comparative example. As illustrated in  FIG. 10 , in this comparative example, the convex portion  82  described above is not provided. For this reason, when the sealing resin  90  is formed, the liquid resin at the time of filling wet-spreads on the first branch portion  51 A. 
     Here, it is not easy to control the wet-spreading of the liquid resin at the time of filling, and thus, it is not easy to control the thickness of the liquid resin filling between the tip end  51 E of the first branch portion  51 A and the wall surface  31 B of the second support resin layer  31 . For this reason, in the extending direction of the sealing resin  90 , a variation occurs in the thickness of the sealing resin  90  covering the first support resin layer  21 . Accordingly, a variation occurs in a reinforcing effect of the first support resin layer  21  by the sealing resin  90 . In addition, a portion which is comparatively thinner than a desired thickness is formed in the sealing resin  90 , and thus, the reinforcing effect of the first support resin layer  21  by the sealing resin  90  decreases. Further, in a case where the sealing resin  90  has fluidity due to heat or the like, the sealing resin  90  spreads on the first branch portion  51 A. 
     In contrast, in one or more embodiments, as illustrated in  FIG. 4  or  FIG. 9 , the height H1 from upper surface of the first support resin layer  21  to the distal end of the convex portion  82  is set to be higher than the height H2 from the upper surface of the first support resin layer  21  to the upper surface of the adhesive portion  51 D of the first branch portion  51 A, and thus, the liquid resin at the time of filling is blocked by the convex portion  82 , the second support resin layer  31  and the coating resin layer  40 , and the wet-spreading of the sealing resin  90  in the width direction is restricted. Accordingly, the thickness of the liquid resin filling between the tip end  51 E of the first branch portion  51 A and the wall surface  31 B of the second support resin layer  31  is easily controlled. Accordingly, in the extending direction of the sealing resin  90 , the occurrence of a variation in the thickness of the sealing resin  90  covering the first support resin layer  21  can be suppressed, and thus, the occurrence of the variation in the reinforcing effect of the first support resin layer  21  by the sealing resin  90  can be suppressed. In addition, the entire sealing resin  90  can be formed to have a desired thickness, and thus, it is possible to improve the reinforcing effect of the first support resin layer  21  by the sealing resin  90 . Further, even in a case where the sealing resin  90  has fluidity due to heat or the like, the sealing resin  90  is blocked by the convex portion  82 , the second support resin layer  31  and the coating resin layer  40 , and thus, the wet-spreading of the sealing resin  90  in the width direction is restricted. Similarly, concerning the second wiring body  30 , as illustrated in  FIG. 5 , the height H5 from the upper surface of the second support resin layer  31  to the distal end of the convex portion  84  is set to be higher than the height H6 from the upper surface of the second support resin layer  31  to the upper surface of the adhesive portion  51 F of the second branch portion  51 B, and thus, the same effect as the effect of the first wiring body  20  described above is obtained. 
     In one or more embodiments, the convex portion  82  is integrally formed with the conductive adhesive layer  80  on the upper surface of the first support resin layer  21  so as to be in contact with the tip end  51 E of the first branch portion  51 A, and the convex portion  82  is made of the conductive adhesive material of which the conductive adhesive layer  80  is made. As described above, the convex portion  82  of such a configuration can be formed at the same time of thermo-compression bonding the terminal portion  52 C of the connection wiring body  50  and the terminal portion  22 C of the first wiring body  20  through the conductive adhesive material  81 . Accordingly, a separate process for forming the convex portion  82  is not necessary, and thus, it is possible to reduce man-hour. In addition, since a gap is not formed between the convex portion  82  and the conductive adhesive layer  80  and the entire sealing resin  90  can be formed to have a desired thickness, and thus, it is possible to improve the reinforcing effect of the first support resin layer  21  by the sealing resin  90 . Similarly, concerning the second wiring body  30 , the convex portion  84  is integrally formed with the conductive adhesive layer  80  on the upper surface of the second support resin layer  31  so as to be in contact with the tip end  51 G of the second branch portion  51 B, and the convex portion  84  is made of the conductive adhesive material of which the conductive adhesive layer  80  is made, and thus, the same effect as the effect of the first wiring body  20  described above is obtained. 
     In one or more embodiments, a thickness H3 of the second support resin layer  31  and the coating resin layer  40  formed on the first support resin layer  21  is set to be higher than or equal to the height H1 from the upper surface of the first support resin layer  21  to the distal portion of the convex portion  82 . Accordingly, when the sealing resin  90  is formed, the liquid resin at the time of filling can be prevented from wet-spreading on the upper surface of the coating resin layer  40 . In addition, the sealing resin  90  does not protrude from the upper surface of the coating resin layer  40 , and thus, when the cover panel  70  or the like adheres to the upper surface of the coating resin layer  40 , it is possible to prevent the sealing resin  90  from becoming an obstacle, and it is possible to prevent an unnecessary stress from being generated. Similarly, concerning the second wiring body  30 , a thickness H8 of the coating resin layer  40  formed on the second support resin layer  31  is set to be higher than or equal to the height H5 from the upper surface of the second support resin layer  31  to the distal portion of the convex portion  84 , and thus, the same effect as the effect of the first wiring body  20  described above is obtained. 
     In one or more embodiments, the corner portion  31 C of the cut-out portion  31 A and the corner portion  40 C of the cut-out portion  40 A are filled with the sealing resin  90 , and thus, in a case where a temperature cycle is applied to the second support resin layer  31  or the coating resin layer  40 , it is possible to prevent a crack from occurring in the corner portion  31 C of the cut-out portion  31 A or the corner portion  40 C of the cut-out portion  40 A. 
       FIG. 11  is an enlarged cross-sectional view illustrating the connection portion between the touch sensor  10  and the connection wiring body  50  according to one or more embodiments. The same reference numerals will be applied to the same configurations as those of the embodiments described above, the repeated description will be omitted, and the description of the embodiments described above will be quoted. 
     As illustrated in  FIG. 11 , concerning the connection portion between the touch sensor  10  and the connection wiring body  50  in one or more embodiments, the groove  86  formed by the convex portion  82 , the wall surfaces  31 B and  40 B and the upper surface of the first support resin layer  21  is filled with the sealing resin  90 , and a part of the first branch portion  51 A is coated with one end side of the sealing resin  90  in the width direction. That is, comparing to the embodiments described above, the thickness of the sealing resin  90  covering the first support resin layer  21  increases, and the one end side of the sealing resin  90  in the width direction spreads up to the first branch portion  51 A in a state of being covered with the convex portion  82 . 
     In one or more embodiments, the sealing resin  90  also has a function of reinforcing an adhesive region of the first support resin layer  21  with respect to the adhesive portion  51 D of the first branch portion  51 A, in addition to the function of reinforcing the region of the first support resin layer  21  between the convex portion  82  and the wall surfaces  31 B and  40 B. Accordingly, it is possible to improve reliability of connection between the terminal portion  22 C and the terminal portion  52 C. 
     Here, in one or more embodiments, the convex portion  82  exists on the one side of the sealing resin  90  in the width direction, and the second support resin layer  31  and the coating resin layer  40  exist on the other side, and thus, the liquid resin at the time of filling reliably fills up to the height of the convex portion  82 . Accordingly, in the extending direction of the sealing resin  90 , it is possible to prevent a variation from occurring in the thickness of the sealing resin  90  covering the first support resin layer  21 , and to prevent a variation from occurring in the reinforcing effect of the first support resin layer  21  by the sealing resin  90 . 
       FIG. 12  is an enlarged cross-sectional view illustrating the connection portion between the touch sensor  10  and the connection wiring body  50  according to one or more embodiments. The same reference numerals will be applied to the same configurations as those of the embodiments described above, the repeated description will be omitted, and the description of the embodiments described above will be quoted. 
     As illustrated in  FIG. 12 , concerning the connection portion between the touch sensor  10  and the connection wiring body  50  in one or more embodiments, the convex portion  82  is formed separately from the conductive adhesive layer  80 . Various resin material having insulating properties can be used as a material of which the convex portion  82  of one or more embodiments is made, and for example, an UV curable resin, a thermosetting resin, a thermoplastic resin and the like such as an epoxy resin, an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, a silicone resin, a phenolic resin and a polyimide resin can be exemplified. The groove  86  formed by the convex portion  82 , the wall surfaces  31 B and  40 B and the upper surface of the first support resin layer  21  is filled with the sealing resin  90 . 
     A formation method of the convex portion  82  of one or more embodiments will be described. In one or more embodiments, the convex portion  82  is formed after the terminal portion  52 C of the connection wiring body  50  and the terminal portion  22 C of the first wiring body  20  are thermo-compression bonded through the conductive adhesive layer  80 . 
     First, the resin material is applied along the tip end  51 E of the first branch portion  51 A by using a dispenser. At this time, a deposition height of the resin material is comparatively higher than the height of the upper surface of the adhesive portion  51 D of the first branch portion  51 A. Then, the resin material is cured by a method of heating, irradiation of an ultraviolet ray or the like. Accordingly, the convex portion  82  protruding from the upper surface of the first support resin layer  21  to a height exceeding the upper surface of the adhesive portion  51 D of the first branch portion  51 A is formed. 
       FIG. 13  is an enlarged cross-sectional view illustrating the connection portion between the touch sensor  10  and the connection wiring body  50  according to one or more embodiments. The same reference numerals will be applied to the same configurations as those of the embodiments described above, the repeated description will be omitted, and the description of the embodiments described above will be quoted. 
     As illustrated in  FIG. 13 , concerning the connection portion between the touch sensor  10  and the connection wiring body  50  in one or more embodiments, the convex portion  82  is formed on the adhesive portion  51 D of the first branch portion  51 A. The convex portion  82  is formed to extend in parallel with the tip end  51 E of the first branch portion  51 A. A distance X between the convex portion  82  and the tip end  51 E may be suitably set, and for example, the distance X may be 0. For example, an UV curable resin, a thermosetting resin, a thermoplastic resin and the like such as an epoxy resin, an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, a silicone resin, a phenolic resin and a polyimide resin can be exemplified as the material of which the convex portion  82  of one or more embodiments is made. 
       FIG. 14  is an enlarged plan view illustrating the connection portion between the touch sensor  10  and the connection wiring body  50  according to one or more embodiments. The same reference numerals will be applied to the same configurations as those of the embodiments described above, the repeated description will be omitted, and the description of the embodiments described above will be quoted. 
     As illustrated in  FIG. 14 , concerning the connection portion between the touch sensor  10  and the connection wiring body  50  in one or more embodiments, the convex portion  82  includes: a first convex portion  82 A which is formed from one end to the other end of the tip end  51 E along the tip end  51 E of the first branch portion  51 A; and second convex portions  82 B which are formed on both ends of the first convex portion  82 A in the extending direction. The second convex portions  82 B are formed on the upper surface of the first support resin layer  21  along end portions  51 H on both sides of the first branch portion  51 A in the width direction (a direction orthogonal to the terminal portion  52 C). That is, the convex portion  82  extends along an end surface of a tip end of the first branch portion  51 A and is formed so as to reach the end surface of the first branch portion  51 A on both sides in the width direction. Accordingly, on both sides of the first branch portion  51 A in the width direction, the wet-spreading of the liquid resin at the time of filling can be restricted, and thus, a variation in the thickness of the sealing resin  90  can be further suppressed, and the reinforcing effect of the first support resin layer  21  by the sealing resin  90  can be further stabilized. 
     The convex portion  84  includes: a first convex portion  84 A which is formed from the one end to the other end of the tip end  51 G along the tip end  51 G of the second branch portion  51 B; and second convex portions  84 B which are formed on both ends of the first convex portion  84 A in the extending direction. The second convex portion  84 B is formed on the upper surface of the second support resin layer  31  along end portions  51 I on both sides of the second branch portion  51 B in the width direction (a direction orthogonal to the terminal portion  53 C). That is, the convex portion  84  extends along an end surface of a tip end of the second branch portion  51 B and is formed so as to reach the end surface of the second branch portion  51 B on both sides in the width direction. Accordingly, on both sides of the second branch portion  51 B in the width direction, the wet-spreading of the liquid resin at the time of filling can be restricted, and thus, a variation in the thickness of the sealing resin  90  can be further suppressed, and the reinforcing effect of the second support resin layer  31  by the sealing resin  90  can be further stabilized.
