     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Modes for carrying out the present invention (embodiments) will be described in detail with reference to the drawings. The present invention is not limited by the description of embodiments below. The components described below include those easily conceived by those skilled in the art and those substantially equivalent. The configurations described below can be combined as appropriate. The configurations are susceptible to a variety of omission, substitution, and modification without departing from the spirit of the invention. 
     Embodiments 
     A carbon decorative panel (resin decorative part)  1  and a dial plate  100  according to an embodiment will be described.  FIG. 1  is a front view illustrating a configuration example of the dial plate  100  according to an embodiment.  FIG. 2  is a sectional view illustrating a configuration example of the dial plate  100  according to the embodiment.  FIG. 3  is an exploded perspective view illustrating a configuration example of the dial plate  100  according to the embodiment.  FIG. 3  schematically illustrates the features of the layered structure of the dial plate  100 .  FIG. 4  is a side view illustrating a first step of imprinting in the dial plate  100  according to the embodiment.  FIG. 5  is a side view illustrating a second step of imprinting in the dial plate  100  according to the embodiment.  FIG. 6  is a side view illustrating a third step of imprinting in the dial plate  100  according to the embodiment.  FIG. 7  is a sectional view illustrating a configuration example of a unit pattern  12   c  according to the embodiment.  FIG. 8  is a perspective view illustrating a configuration example of the unit pattern  12   c  according to the embodiment.  FIGS. 9A to 9G  are plan views illustrating an example of a top portion inclination D of the unit pattern  12   c  according to the embodiment.  FIG. 10  is a plan view illustrating a carbon-toned pattern M according to the embodiment. 
     As illustrated in  FIG. 1 , the carbon decorative panel  1  is applied to the dial plate  100  as a resin decorative part having a carbon-toned pattern M. The dial plate  100  is applied to a vehicle indicator (not illustrated) mounted on a vehicle. The vehicle indicator constitutes a vehicle-mounted meter and, for example, is mounted on an instrument panel provided in the dashboard of a vehicle to display a variety of information related to the vehicle as information available for driving the vehicle. 
     The dial plate  100  is, for example, a dial plate for a speedometer and formed as a circular flat plate. The dial plate  100  has a through hole  101  at the center, in which a not-illustrated pointer is inserted. The dial plate  100  has a plurality of character display sections (design display sections)  16   a  in the circumferential direction near the outer periphery to show the speed. For example, each character display section  16   a  emits light radiating from a light source (not illustrated) arranged in the dial plate  100  on the opposite side to the viewer side viewed by the driver, to the viewer side. The driver then can recognize a character in the character display section  16   a  that shows the vehicle speed in the dial plate  100 . Although  FIG. 1  partially illustrates the carbon-toned pattern M, the carbon-toned pattern M is provided, for example, in a region excluding the regions of the character display sections  16   a.    
     As used herein the depth direction of the dial plate  100  typically corresponds to the front-back direction of the vehicle to which the dial plate  100  is applied. The front surface side of the dial plate  100  is the side facing the driver&#39;s seat of the vehicle and typically the viewer side viewed by the driver sitting in the driver&#39;s seat, that is, the driver&#39;s eyepoint EP side. By contrast, the rear surface side of the dial plate  100  is the opposite side to the front surface side in the depth direction and typically the side accommodated in the inside of the instrument panel. 
     As illustrated in  FIG. 2 , the dial plate  100  includes a carbon decorative panel  1 , an anti-glare (AG) print layer  13  as a low reflection layer, a design layer  16 , and a smoke layer  17 . The carbon decorative panel  1  includes a clear decoration  10 , a carbon color layer  14 , and a light-blocking print layer  15 . As illustrated in  FIG. 3 , in the dial plate  100 , the AG print layer  13 , the clear decoration  10 , the carbon color layer  14 , and the light-blocking print layer  15  are layered in this order from the front surface side to the rear surface side in the depth direction. 
     The clear decoration  10  has a body  10   a  that transmits light of wavelengths in the visible light range. The body  10   a  includes a substrate  11  and a clear layer  12 . The substrate  11  serves as the base of the dial plate  100 . The substrate  11  is formed of, for example, a resin material such as acrylic resin and polycarbonate that transmits light of wavelengths in the visible light range. The substrate  11  is formed by shaping a resin material into a desired flat plate shape, for example, using a mold. 
     The clear layer  12  has a carbon-toned pattern M. The clear layer  12  is provided by imprinting described later on the opposite side to the viewer side of the substrate  11 , that is, on the rear surface side of the substrate  11 . The clear layer  12  is formed of, for example, a photocurable resin material (ink) that transmits light of wavelengths in the visible light range and is cured when irradiated with ultraviolet (UV) rays. As illustrated in  FIG. 2 , the clear layer  12  includes a carbon-toned irregular surface  12   a . The carbon-toned irregular surface  12   a  is provided on the clear layer  12  on the opposite side to the substrate  11 , and a plurality of projections and depressions  12   b  form the carbon-toned pattern M. The protrusions and depressions  12   b  constitute a plurality of unit patterns  12   c . Each unit pattern  12   c  constitutes a weave of pseudo carbon fiber bundles presenting actual pre-impregnated carbon fiber bundles in a pseudo manner, in which each individual pseudo carbon fiber presenting an actual carbon fiber in a pseudo manner is formed. As used herein pre-impregnation refers to the woven actual carbon fibers impregnated with resin and cured. The unit pattern  12   c  has a top portion  12   d  and a pair of curved portions  12   e . The top portion  12   d  is positioned at the center of the unit, pattern  12   c  in the extending direction of a pseudo carbon fiber bundle. A pair of curved portions  12   e  are positioned on both sides of the top portion  12   d  in the extending direction of a pseudo carbon fiber bundle and are formed in a curved shape. The top portion  12   d  of the unit pattern  12   c  is formed in a concave shape from the opposite side to the viewer side toward the viewer side. 
     The AG print layer  13  suppresses reflection of light. The AG print layer  13  is laminated on the viewer side of the substrate  11  and provided over the entire surface of the substrate  11 . The AG print layer  13  is formed, for example, by screen printing on the viewer side of the substrate  11 . The AG print layer  13  has minute protrusions and depressions on the viewer side of the substrate  11 . The AG print layer  13  diffuses incident light L 1  incident from the viewer side on the minute protrusions and depressions to suppress regular reflection of incident light L 1  on the surface of the substrate  11  on the viewer side. 
     The carbon color layer  14  is a colored layer colored in a carbon color. As used herein carbon color is, for example, black (carbon black). The carbon color layer  14  is laminated on the clear layer  12  on the carbon-toned irregular surface  12   a  side. The carbon color layer  14  is formed, for example, by printing ink of a resin material on the carbon-toned irregular surface  12   a . The carbon color layer  14  is formed, for example, by screen printing. For example, a screen printer prints ink colored in the carbon color on the carbon-toned irregular surface  12   a . The screen printer prints ink, for example, in the region excluding the region of the character display section  16   a  and the region of an indicator display section (design display section)  17   a  on the carbon-toned irregular surface  12   a . The carbon-toned pattern M thus does not appear in the region of the character display section  16   a  and the region of the indicator display section  17   a.    
     The carbon color layer  14  includes a base material of a resin material colored in the carbon color and a bright material added to the base material and does not transmit light. The bright material has a refractive index different from that of the resin material of the clear layer  12  and has a gloss. The bright material includes, for example, aluminum, silver, or pearl. The carbon color layer  14  has a reflective surface  14   a  on the carbon-toned irregular surface  12   a  side. The reflective surface  14   a  is provided in contact with the protrusions and depressions  12   b  of the carbon-toned irregular surface  12   a  and has the shape of the carbon-toned irregular surface  12   a . That is, the reflective surface  14   a  has the same shape as the shape of each unit pattern  12   c  of the carbon-toned irregular surface  12   a . Specifically, a portion of the reflective surface  14   a  that is in contact with the top portion  12   d  of the unit pattern  12   c  is formed in a concave shape from the opposite side to the viewer side toward the viewer side as viewed from the viewer (eyepoint EP) side. In this way, in the reflective surface  14   a , a weave of pseudo carbon fiber bundles is formed as viewed from the viewer (eyepoint EP) side, and each individual pseudo carbon fiber is formed. The reflective surface  14   a  reflects incident light L 1  transmitted through the clear decoration  10  toward the viewer side as reflected light  12 . 
     The light-blocking print layer  15  is a light-blocking layer that blocks light. The light-blocking print layer  15  is laminated on the carbon color layer  14  on the opposite side to the viewer side. The light-blocking print layer  15  is formed, for example, by printing ink of a resin material on the carbon color layer  14 . The light-blocking print layer  15  is formed, for example, using a screen printer. The screen printer prints ink colored in a light-blocking color on the rear surface side of the carbon color layer  14 . The screen printer prints ink on the rear surface side of the carbon color layer  14 , for example, in a region excluding the region of the character display section  16   a  and the region of the indicator display section  17   a . The light-blocking print layer  15  blocks light incident from the opposite side (rear surface side) to the viewer side. 
     The design layer  16  forms the character display section  16   a . The character display section  16   a  transmits light such that a design related to the vehicle is illuminated. The design layer  16  is laminated on the carbon-toned irregular surface  12   a  side of the clear layer  12 . The design layer  16  is formed, for example, by printing ink of a resin material in the region of the character display section  16   a  in the clear layer  12 . The design layer  16  is formed, for example, using a screen printer. The screen printer prints translucent ink colored in a desired color in the region of the character display section  16   a  in the clear layer  12 . The design layer  16  transmits light emitted from a light source (not illustrated) provided on the opposite side (rear surface side) to the viewer side and emits the transmitted light to the clear layer  12 . The character display section  16   a  shows a vehicle speed in the dial plate  100  in a display manner in which the carbon-toned pattern M is not superimposed. 
     The smoke layer  17  forms the indicator display section  17   a . The indicator display section  17   a  transmits light such that a design related to the vehicle is illuminated. The smoke layer  17  is laminated on the carbon-toned irregular surface  12   a  side of the clear layer  12 . The smoke layer  17  is formed, for example, by printing ink of a resin material in the region of the indicator display section  17   a  in the clear layer  12 . The smoke layer  17  is formed, for example, using a screen printer. The screen printer prints ink colored in a light-reducing color in the region of the indicator display section  17   a  in the clear layer  12 . The smoke layer  17  transmits light emitted from a light source (not illustrated) provided on the opposite side (rear surface side) to the viewer side and emits the transmitted light to the clear layer  12 . The indicator display section  17   a  shows an indicator on the dial plate  100  in a display manner in which the carbon-toned pattern M is not superimposed. 
     Referring now to  FIG. 4  to  FIG. 6 , the steps of imprinting in the dial plate  100  are described. The operator performs imprinting using an imprinting system  2 . The imprinting system  2  includes a mold  2   a , a roller  2   b , and a UV metal-halide lamp  2   c . The mold  2   a  has a plurality of protrusions and depressions  2   d  on its surface for forming the unit patterns  12   c  of the carbon-toned pattern M. As illustrated in  FIG. 4 , the operator first pours a liquid photocurable resin material (ink) onto the surface of the mold  2   a  with the protrusions and depressions  2   d . As illustrated in  FIG. 5 , the operator then operates the imprinting system  2  to press the substrate  11  against the photocurable resin material poured on the surface of the mold  2   a  using the roller  2   b  while irradiating the photocurable resin material with UV light using the UV metal-halide lamp  2   c  to cure the photocurable resin material. As illustrated in  FIG. 6 , the operator then operates the imprinting system  2  to move the photocurable resin material (clear layer  12 ) laminated on the substrate  11  away from the mold  2   a . The clear decoration  10  with the carbon-toned irregular surface  12   a  thus can be formed. 
     Referring now to  FIG. 7  and  FIG. 8 , the unit pattern  12   c  will be described in detail. The unit pattern  12   c  is formed in a rectangular shape when viewed from the viewer side. The unit pattern  12   c  has the top portion  12   d  and a pair of curved portions  12   e  as described above. The unit pattern  12   c  has the top portion  12   d  formed to be concave from the opposite side to the viewer side toward the viewer side. 
     The top portion  12   d  is formed in an ellipse shape (for example, oval shape) when viewed from the viewer side, and formed to be flat. The top portion  12   d  is formed, for example, such that the boundary line k of the top portion  12   d  and a pair of curved portions  12   e  is formed with an arc-shaped curve protruding from the top portion  12   d  side toward the curved portion  12   e  side. The top portion  12   d  is positioned at the center of the unit pattern  12   c  in the extending direction of the pseudo carbon fiber bundle, that is, in the long side direction of the unit pattern  12   c . The top portion  12   d  is positioned at the center of the unit pattern  12   c  in the short side direction orthogonal to the long side direction of the unit pattern  12   c . The top portion  12   d  is formed, for example, over the entire width of the unit pattern  12   c  in the short side direction. 
     A pair of curved portions  12   e  are positioned on both sides of the top portion  12   d  in the extending direction of the pseudo carbon fiber bundle. The section of a pair of curved portions  12   e  along the extending direction of a pair of curved portions  12   e  (that is, the extending direction of the pseudo carbon fiber bundle) is formed in a curved shape (for example, arc shape) protruding from the rear surface side toward the viewer side. The curvature of a pair of curved portions  12   e  in the section along the extending direction of a pair of curved portions  12   e  is greater on the center portion  12   i  side than on the end portion  12   j  side in the crossing direction that crosses the extending direction. For example, the curvature of a pair of curved portions  12   e  is largest at the center portion  12   i , smaller as the distance from the center portion  12   i  increases along the crossing direction, and smallest at both end portions  12   j , in the crossing direction. With this configuration, the top portion  12   d  of the unit pattern  12   c  can be formed in an ellipse shape (for example, oval shape) and the top portion  12   d  can be formed to be flat. 
     The carbon-toned pattern M of the carbon-toned irregular surface  12   a  will now be described in detail. The carbon-toned pattern M presents a twill weave pattern in a pseudo manner. As used herein the twill weave pattern refers to, for example, a weaving method in which a row in the longitudinal direction and a row in the lateral direction of carbon fibers cross every two rows. For example, as illustrated in  FIG. 10 , the carbon-toned pattern M is formed of unit patterns  12   c  ( 121   c  to  127   c ) in which the extending direction of each pseudo carbon fiber bundle coincides with the long side direction of the unit pattern  12   c  ( 121   c  to  127   c ) and the long side direction crosses (is orthogonal to) one another. 
     The carbon-toned irregular surface  12   a  may include at least two kinds of unit patterns  12   c  ( 121   c  to  127   c ) with different inclinations of the top portions  12   d . For example, as illustrated in  FIG. 9A  to  FIG. 9G , the carbon-toned irregular surface  12   a  includes seven kinds of unit patterns  121   c  to  127   c  with different top portion inclinations D of the top portions  12   d . Here, the top portion inclination D is the inclination of the long axis (center line) P 1  relative to the reference line Q. The reference line Q is a line along the extending direction of the pseudo carbon fiber bundle. The long axis P 1  as the axis along the long side direction of the top portion  12   d.    
     The top portion inclinations D of the unit patterns  121   c  to  127   c  vary stepwise so as to gradually rotate counterclockwise as viewed from the viewer side. For example, the top portion inclinations D of the unit patterns  121   c  to  127   c  vary stepwise so as to gradually rotate counterclockwise as viewed from the viewer side in the order of the unit pattern  121   c  illustrated in  FIG. 9A , the unit pattern  122   c  illustrated in  FIG. 9B , the unit pattern  123   c  illustrated in  FIG. 9C , the unit pattern  124   c  illustrated in  FIG. 9D , the unit pattern  125   c  illustrated in  FIG. 9E , the unit pattern  126   c  illustrated in  FIG. 9F , and the unit pattern  127   c  illustrated in  FIG. 9G . The top portions  12   d  of the unit patterns  121   c  to  127   c  may have the same ellipse shape, or the top portions  12   d  may have different ellipse shapes. That is, in the unit patterns  121   c  to  127   c , the top portion inclinations D of the top portions  12   d  should be different from each other. 
     The carbon-toned irregular surface  12   a  has the appropriately arranged unit patterns  121   c  to  127   c  to represent slight changes of carbon fiber bundles produced when actual carbon fiber bundles are woven by pre-impregnation. In the carbon-toned irregular surface  12   a , the unit patterns  121   c  to  127   c  are arranged such that the top portion inclination D varies stepwise in the unit patterns  121   c  to  127   c  that are adjacent to each other and in which the extending direction of the pseudo carbon fiber bundle is the same direction. For example, as illustrated in  FIG. 10 , in the carbon-toned irregular surface  12   a , when the extending direction of the pseudo carbon fiber bundle is the same direction, the unit patterns  121   c  to  127   c  are arranged such that the change of the top portion inclination D is smallest in the adjacent unit patterns  121   c  to  127   c  in accordance with the rotation direction. In the carbon-toned irregular surface  12   a , for example, the unit pattern  125   c  or the unit pattern  127   c  is arranged adjacent to the unit pattern  126   c.    
     As described above, the carbon decorative panel  1  according to the embodiment includes the clear decoration  10  having the body  10   a  transmitting light and including the carbon-toned irregular surface  12   a  provided on the body  10   a  and having the carbon-toned pattern M formed with the protrusions and depressions  12   b . The carbon-toned irregular surface  12   a  has the unit patterns  12   c  that constitute a weave of pseudo carbon fiber bundles presenting carbon fiber bundles in a pseudo manner, as the protrusions and depressions  12   b  that form the carbon-toned pattern. M. The unit patterns  12   c  each have the top portion  12   d  positioned at the center in the extending direction of the pseudo carbon fiber bundle. The unit patterns  12   c  include at least two kinds of unit patterns  12   c  with different top portion inclinations D, where the top portion inclination D is the inclination of the long axis P 1  along the long side direction of the top portion  12   d  relative to the reference line Q along the extending direction. 
     With this configuration, in the carbon decorative panel  1 , the top portion inclinations D of the top portions  12   d  can be formed in various patterns to achieve the resemblance to the top portions of the protrusion and depression shape of an actual carbon member. In the carbon decorative panel  1 , therefore, the unit patterns  12   c  having irregularity that appears as if actual pre-impregnated carbon fiber bundles are woven and pressed can be formed. The carbon decorative panel  1  therefore can achieve change of highlights like an actual carbon member and achieve the appearance that resembles an actual carbon member. The carbon decorative panel  1  therefore can appropriately ensure the texture of the carbon-toned pattern M. 
     In the above-described carbon decorative panel  1 , the top portion inclination D of the top portion  12   d  varies stepwise in the unit patterns  12   c  that are adjacent to each other and in which the extending direction of the pseudo carbon fiber bundle is the same direction. With this configuration, the carbon decorative panel  1  can represent a pattern in which actual pre-impregnated carbon fiber bundles continuously change in a pseudo manner and achieve the appearance that resembles an actual carbon member. 
     In the above-described carbon decorative panel  1 , the carbon-toned pattern M is a twill weave pattern including the unit patterns  12   c  in which the extending direction of the pseudo carbon fiber bundle coincides with the long side direction of the unit pattern  12   c  and the long side direction crosses one another. With this configuration, the carbon decorative panel  1  can achieve the appearance that resembles an actual carbon member in a twill weave pattern. 
     In the above-described carbon decorative panel  1 , the unit patterns  12   c  each have a pair of curved portions  12   e  positioned on both sides of the top portion  12   d  in the extending direction and formed in a curved shape. The curvature of a pair of curved portions  12   e  in the section along the extending direction of a pair of curved portions  12   e  is greater on the center portion  12   i  side than on the end portion  12   j  side in the crossing direction that crosses the extending direction. With this configuration, in the carbon decorative panel  1 , when viewed from the viewer side, the top portion  12   d  of the unit pattern  12   c  can be formed in an ellipse shape (for example, oval shape), and the top portion  12   d  can be formed to be flat. With this configuration, the carbon decorative panel  1  can achieve the appearance that resembles an actual carbon member. 
     In the above-described carbon decorative panel  1 , the boundary line k of the top portion  12   d  and a pair of curved portions  12   e  is an arc-shaped curve protruding from the top portion  12   d  side toward the curved portion  12   e  side. With this configuration, in the carbon decorative panel  1 , the top portion  12   d  of the unit pattern  12   c  can be formed in an ellipse shape (for example, oval shape) when viewed from the viewer side, and the appearance that resembles an actual carbon member can be achieved. 
     The above-described carbon decorative panel  1  includes the carbon color layer  14  colored in the carbon color and reflecting light. The carbon-toned irregular surface  12   a  is provided on the opposite side to the viewer side of the body  10   a , and the top portions  12   d  of the unit patterns  12   c  are formed to be concave from the opposite side to the viewer side toward the viewer side. The carbon color layer  14  is laminated on the carbon-toned irregular surface  12   a  and includes the reflective surface  14   a  provided in contact with the unit patterns  12   c  to reflect light transmitted through the clear decoration  10 . With this configuration, the carbon decorative panel  1  can represent the carbon-toned pattern M by reflected light L 2  reflected by the reflective surface  14   a  of the carbon color layer  14  that presents actual pre-impregnated carbon fiber bundles in a pseudo manner. With this configuration, the carbon decorative panel  1  can represent reflected light reflected by the reflective surface of actual pre-impregnated carbon fiber bundles in a pseudo manner. With this configuration, the carbon decorative panel  1  can achieve the appearance that resembles an actual pre-impregnated carbon member. The carbon decorative panel  1  therefore can appropriately ensure the texture of the carbon-toned pattern M. 
     The dial plate  100  according to an embodiment includes a clear decoration  10 , an AG print layer  13 , a character display section  16   a  (design layer  16 ), and an indicator display section  17   a  (smoke layer  17 ). The clear decoration  10  has a body  10   a  provided in a vehicle and transmitting light and includes a carbon-toned irregular surface  12   a  provided on the body  10   a  and having a carbon-toned pattern M formed with the protrusions and depressions  12   b . The AG print layer  13  is laminated on the viewer side of the body  10   a  and suppresses reflection of light. The character display section  16   a  and the indicator display section  17   a  are provided on the body  10   a  and transmit light such that a design related to the vehicle is illuminated. The carbon-toned irregular surface  12   a  has the unit patterns  12   c  that constitute a weave of pseudo carbon fiber bundles presenting carbon fiber bundles in a pseudo manner, as the protrusions and depressions  12   b  that form the carbon-toned pattern M. The patterns  12   c  each have the top portion  12   d  positioned at the center in the extending direction of the pseudo carbon fiber bundle and include at least two kinds of unit patterns  12   c  with different top portion inclinations D, where the top portion inclination D is the inclination of the long axis P 1  along the long side direction of the top portion  12   d  relative to the reference line Q along the extending direction. With this configuration, the dial plate  100  can achieve the effects equivalent to those of the above-described carbon decorative panel  1 . 
     Modifications 
     Modifications of the embodiment will now be described  FIG. 11  is a sectional view illustrating a configuration example of a dial plate  100 A according to a first modification of the embodiment.  FIG. 12  is a sectional view illustrating a configuration example of a unit pattern  12   v  according to the first modification of the embodiment.  FIG. 13  is a perspective view illustrating a configuration example of the unit pattern  12   v  according to the first modification of the embodiment. As illustrated in  FIG. 11 , a carbon decorative panel  1 A according to the first modification differs from the carbon decorative panel  1  according to the embodiment in that the carbon-toned irregular surface  12   a  of the clear layer  12 A is formed to be convex from the viewer side toward the opposite side to the viewer side. In the carbon decorative panel  1 A according to the first modification, the components equivalent to those in the carbon decorative panel  1  according to the embodiment are denoted by the same reference signs and a detailed description thereof is omitted. 
     The carbon decorative panel  1 A includes a clear decoration  10 A, a carbon color layer  14 , and a light-blocking print layer  15 . The clear decoration  10 A has a substrate  11  and a clear layer  12 A. 
     The clear layer  12 A has a carbon-toned pattern M. The clear layer  12 A is provided on the rear surface side of the substrate  11  by imprinting. For example, the clear layer  12 A is formed of a photocurable resin material (ink) that transmits light of wavelengths in the visible light range and is cured when irradiated with UV light. The clear layer  12 A includes a carbon-toned irregular surface  12   a . The carbon-toned irregular surface  12   a  is provided on the clear layer  12 A on the opposite side to the substrate  11  and has the carbon-toned pattern M formed with a plurality of protrusions and depressions. The protrusions and depressions form a plurality of unit patterns  12   v . Each unit pattern  12   v  constitutes a weave of pseudo carbon fiber bundles presenting actual pre-impregnated carbon fiber bundles in a pseudo manner, in which each individual pseudo carbon fiber presenting an actual carbon fiber in a pseudo manner is formed. As illustrated in  FIG. 12  and  FIG. 13 , the unit pattern  12   v  has a top portion  12   u  and a pair of curved portions  12   t . The top portion  12   u  of the unit pattern  12   v  is formed to be convex from the viewer side toward the opposite side to the viewer side. 
     The top portion  12   u  is formed in an ellipse shape (for example, oval shape) when viewed from the viewer side, and formed to be flat. The top portion  12   u  is formed, for example, such that the boundary line k of the top portion  12   u  and a pair of curved portions  12   t  is formed with an arc-shaped curve protruding from the top portion  12   u  side toward the curved portion  12   t  side. The top portion  12   u  is positioned at the center of the unit pattern  12   v  in the extending direction of the pseudo carbon fiber bundle, that is, in the long side direction of the unit pattern  12   v . The top portion  12   u  is positioned at the center of the unit pattern  12   v  in the short side direction orthogonal to the long side direction of the unit pattern  12   v . The top portion  12   u  is formed, for example, over the entire width of the unit pattern  12   v  in the short side direction. 
     A pair of curved portions  12   t  are positioned on both sides of the top portion  12   u  in the extending direction of the pseudo carbon fiber bundle. The section of a pair of curved portions  12   t  along the extending direction of a pair of curved portions  12   t  (that is, the extending direction of the pseudo carbon fiber bundle) is formed in a curved shape (for example, arc shape) protruding from the viewer side toward the rear surface side. The curvature of a pair of curved portions  12   t  in the section along the extending direction of a pair of curved portions  12   t  is greater on the center portion  12   i  side than on the end portion  12   j  side in the crossing direction that crosses the extending direction. For example, the curvature of a pair of curved portions  12   t  is largest at the center portion  12   i , smaller as the distance from the center portion  12   i  increases along the crossing direction, and smallest at both end portions  12   j , in the crossing direction. With this configuration, the top portion  12   u  of the unit pattern  12   v  can be formed in an ellipse shape (for example, oval shape) and the top portion  12   u  can be formed to be flat. 
     The carbon-toned irregular surface  12   a  includes at least two kinds of unit patterns  12   v  with different inclinations of the top portions  12   u . The carbon-toned irregular surface  12   a  may include, for example, seven kinds of unit patterns  12   v  with different top portion inclinations D of the top portions  12   u . In this case, the top portion inclination D of the top portion  12   u  varies stepwise in the unit patterns  12   v  that are adjacent to each other and in which the extending direction of the pseudo carbon fiber bundle is the same direction. The reflective surface  14   a  between the clear decoration  10 A and the carbon color layer  14  reflects incident light L 1  transmitted through the clear decoration  10 A toward the viewer side as reflected light  12 . 
     As described above, the carbon decorative panel  1 A according to the modification of the embodiment includes the clear decoration  10 A having the body  10   a  transmitting light and including the carbon-toned irregular surface  12   a  provided on the body  10   a  and having the carbon-toned pattern M formed with the protrusions and depressions  12   b . The carbon-toned irregular surface  12   a  has the unit patterns  12   v  that constitute a weave of pseudo carbon fiber bundles presenting carbon fiber bundles in a pseudo manner, as the protrusions and depressions  12   b  that form the carbon-toned pattern M. The unit patterns  12   v  each have the top portion  12   u  positioned at the center in the extending direction of the pseudo carbon fiber bundle. The unit patterns  12   v  include at least two kinds of unit patterns  12   v  with different top portion inclinations D, where the top portion inclination D is the inclination of the above-noted long axis P 1  along the long side direction of the top portion  12   u  relative to the reference line Q along the extending direction. 
     With this configuration, in the carbon decorative panel  1 A, the top portion inclinations D of the top portions  12   u  can be formed in various patterns to achieve the resemblance to the top portions of the projection and depression shape of an actual carbon member. In the carbon decorative panel  1 A, therefore, the unit patterns  12   v  having irregularity that appears as if actual pre-impregnated carbon fiber bundles are woven and pressed can be formed. The carbon decorative panel  1 A therefore can achieve change of highlights like an actual carbon member and achieve the appearance that resembles an actual carbon member. The carbon decorative panel  1 A therefore can appropriately ensure the texture of the carbon-toned pattern M.

     The clear layer  12 B has a carbon-toned pattern M. The clear layer  12 B is provided by imprinting on the front surface side of the substrate  11 . The clear layer  12 B is formed of, for example, a photocurable resin material (ink) that transmits light of wavelengths in the visible light range and is cured when irradiated with UV light. The clear layer  12 B includes a carbon-toned irregular surface  12   a . The carbon-toned irregular surface  12   a  is provided on the viewer side of the clear layer  12 B and has the carbon-toned pattern M formed with a plurality of projections and depressions. The projections and protrusions constitute a plurality of unit patterns  12   f . Each unit pattern  12   f  constitutes a weave of pseudo carbon fiber bundles presenting actual pre-impregnated carbon fiber bundles in a pseudo manner, and each individual pseudo carbon fiber presenting an actual carbon fiber in a pseudo manner is formed. The unit pattern  12   f  has a top portion  12   g  and a pair of curved portions  12   h . As illustrated in  FIG. 15  and  FIG. 16 , the unit pattern  12   f  has the top portion  12   g  formed to be convex from the opposite side to the viewer side toward the viewer side. 
     The top portion  12   g  is formed in an ellipse shape (for example, oval shape) when viewed from the viewer side, and formed to be flat. The top portion  12   g  is formed, for example, such that the boundary line k of the top portion  12   g  and a pair of curved portions  12   h  is formed with an arc-shaped curve protruding from the top portion  12   g  side toward the curved portion  12   h  side. The top portion  12   g  is positioned at the center of the unit pattern  12   f  in the extending direction of the pseudo carbon fiber bundle, that is, in the long side direction of the unit pattern  12   f . The top portion  12   g  is positioned at the center of the unit pattern  12   f  in the short side direction orthogonal to the long side direction of the unit pattern  12   f . The top portion  12   g  is formed, for example, over the entire width of the unit pattern  12   f  in the short side direction. 
     A pair of curved portions  12   h  are positioned on both sides of the top portion  12   g  in the extending direction of the pseudo carbon fiber bundle. The section of a pair of curved portions  12   h  along the extending direction of a pair of curved portions  12   h  (that is, the extending direction of the pseudo carbon fiber bundle) is formed in a curved shape (for example, arc shape) protruding from the rear surface side toward the viewer side. The curvature of a pair of curved portions  12   h  in the section along the extending direction of a pair of curved portions  12   h  is greater on the center portion  12   i  side than on the end portion  12   j  side in the crossing direction that crosses the extending direction. For example, the curvature of a pair of curved portions  12   h  is largest at the center portion  12   i , smaller as the distance from the center portion  12   i  increases along the crossing direction, and smallest at both end portions  12   j , in the crossing direction. With this configuration, the top portion  12   g  of the unit pattern  12   f  can be formed in an ellipse shape (for example, oval shape) and the top portion  12   g  can be formed to be flat. A clear decoration  10 B reflects part of incident light L 1  incident on the carbon-toned irregular surface  12   a  toward the viewer side and transmits the other part of incident light L 1  incident on the carbon-toned irregular surface  12   a  toward the colored layer  19  side. 
     The carbon-toned irregular surface  12   a  includes at least two kinds of unit patterns  12   f  with different inclinations of the top portions  12   g . The carbon-toned irregular surface  12   a  may include, for example, seven kinds of unit patterns  12   f  with different top portion inclinations D of the top portions  12   g . In this case, the top portion inclination D of the top portion  12   g  varies stepwise in the unit patterns  12   f  that are adjacent to each other and in which the extending direction of the pseudo carbon fiber bundle is the same direction. 
     As described above, the carbon decorative panel  1 B according to the modification of the embodiment includes the colored layer  19  laminated on the opposite side to the viewer side of the body  10   a  and colored in the carbon color. The carbon-toned irregular surface  12   a  is provided on the viewer side of the body  10   a , and the top portions  12   g  of the unit patterns  12   f  are formed to be convex from the opposite side to the viewer side toward the viewer side.

     With this configuration, in the carbon decorative panel  1 B, the top portion inclinations D of the top portions  12   g  can be formed in various patterns to achieve the resemblance to the pattern of the protrusion and depression shape of an actual carbon member. In the carbon decorative panel  1 B, therefore, the unit patterns  12   f  having irregularity that appears as if actual pre-impregnated carbon fiber bundles are woven and pressed can be formed. The carbon decorative panel  1 B therefore can achieve change of highlights like an actual carbon member and achieve the appearance that resembles an actual carbon member. The carbon decorative panel  1 B therefore can appropriately ensure the texture of the carbon-toned pattern M.

FIG. 18  is a sectional view illustrating a configuration example of a unit pattern  12   s  according to the third modification of the embodiment.  FIG. 19  is a perspective view illustrating a configuration example of the unit pattern  12   s  according to the third modification of the embodiment. As illustrated in  FIG. 17 , a carbon decorative panel  1 C according to the third modification differs from the carbon decorative panel  1 B according to the second modification in that the carbon-toned irregular surface  12   a  of the clear layer  12 C is formed to be concave toward the viewer side. In the carbon decorative panel  1 C according to the third modification, the components equivalent to those in the carbon decorative panel  1 B according to the second modification are denoted by the same reference signs and a detailed description thereof is omitted. 
     The carbon decorative panel  1 C includes a substrate  11 , a colored layer  19  laminated on the rear surface side of the substrate  11  and colored in a carbon color, and a concave clear layer  12 C laminated on the front surface side of the substrate  11 . 
     The clear layer  12 C has a carbon-toned pattern M formed with a plurality of projections and depressions. The projections and protrusions constitute a plurality of unit patterns  12   s . Each unit pattern  12   s  constitutes a weave of pseudo carbon fiber bundles presenting actual pre-impregnated carbon fiber bundles in a pseudo manner, and each individual pseudo carbon fiber presenting an actual carbon fiber in a pseudo manner is formed. The unit pattern  12   s  has a top portion  12   r  and a pair of curved portions  12   q . As illustrated in  FIG. 18  and  FIG. 19 , the unit pattern  12   s  is formed to be concave as viewed from the viewer side. 
     The top portion  12   r  is formed in an ellipse shape (for example, oval shape) when viewed from the viewer side, and formed to be flat. The top portion  12   r  is formed, for example, such that the boundary line k of the top portion  12   r  and a pair of curved portions  12   q  is formed with an arc-shaped curve protruding from the top portion  12   r  side toward the curved portion  12   q  side. The top portion  12   r  is positioned at the center of the unit pattern  12   s  in the extending direction of the pseudo carbon fiber bundle, that is, in the long side direction of the unit pattern  12   s . The top portion  12   r  is positioned at the center of the unit pattern  12   s  in the short side direction orthogonal to the long side direction of the unit pattern  12   s . The top portion  12   r  is formed, for example, over the entire width of the unit pattern  12   s  in the short side direction. 
     A pair of curved portions  12   q  are positioned on both sides of the top portion  12   r  in the extending direction of the pseudo carbon fiber bundle. The section of a pair of curved portions  12   q  along the extending direction of a pair of curved portions  12   q  (that is, the extending direction of the pseudo carbon fiber bundle) is formed in a curved shape (for example, arc shape) depressed from the viewer side toward the rear surface side. The curvature of a pair of curved portions  12   q  in the section along the extending direction of a pair of curved portions  12   q  is greater on the center portion  12   i  side than on the end portion  12   j  side in the crossing direction that crosses the extending direction. For example, the curvature of a pair of curved portions  12   q  is largest at the center portion  12   i , smaller as the distance from the center portion  12   i  increases along the crossing direction, and smallest at both end portions  12   j , in the crossing direction. With this configuration, the top portion  12   r  of the unit pattern  12   s  can be formed in an ellipse shape (for example, oval shape) and the top portion  12   r  can be formed to be flat. A clear decoration  10 C reflects part of incident light L 1  incident on the carbon-toned irregular surface  12   a  toward the viewer side and transmits the other part of incident light L 1  incident on the carbon-toned irregular surface  12   a  toward the colored layer  19  side. 
     The carbon-toned irregular surface  12   a  includes at least two kinds of unit patterns  12   s  with different inclinations of the top portions  12   r . The carbon-toned irregular surface  12   a  may include, for example, seven kinds of unit patterns  12   s  with different top portion inclinations D of the top portions  12   r . In this case, the top portion inclination D of the top portion  12   r  varies stepwise in the unit patterns  12   s  that are adjacent to each other and in which the extending direction of the pseudo carbon fiber bundle is the same direction. 
     As described above, the carbon decorative panel  1 C according to the modification of the embodiment includes the colored layer  19  laminated on the opposite side to the viewer side of the body  10   a  and colored in the carbon color. The carbon-toned irregular surface  12   a  is provided on the viewer side of the body  10   a , and the top portions  12   r  of the unit patterns  12   s  are formed to be concave from the viewer side toward the opposite side to the viewer side. The clear decoration  10 C reflects part of light incident on the carbon-toned irregular surface  12   a  toward the viewer side and transmits the other part of light incident on the carbon-toned irregular surface  12   a  toward the colored layer  19  side. The carbon-toned irregular surface  12   a  has the unit patterns  12   s  that constitute a weave of pseudo carbon fiber bundles presenting carbon fiber bundles in a pseudo manner. The unit patterns  12   s  each have the top portion  12   r  positioned at the center in the extending direction of the pseudo carbon fiber bundle. The unit patterns  12   s  include at least two kinds of unit, patterns  12   s  with different top portion inclinations D, where the top portion inclination D is the inclination of the long axis P 1  along the long side direction of the top portion  12   r  relative to the reference line Q along the extending direction. 
     With this configuration, in the carbon decorative panel  1 C, the top portion inclinations D of the top portions  12   r  can be formed in various patterns to achieve the resemblance to the pattern of the protrusion and depression shape of an actual carbon member. In the carbon decorative panel  1 C, therefore, the unit patterns  12   s  having irregularity that appears as if actual pre-impregnated carbon fiber bundles are woven and pressed can be formed. The carbon decorative panel  1 C therefore can achieve change of highlights like an actual carbon member and achieve the appearance that resembles an actual carbon member. The carbon decorative panel  1 C therefore can appropriately ensure the texture of the carbon-toned pattern M. 
     The pseudo carbon fiber bundle may have a plurality of linear grooves (not illustrated) that constitute pseudo carbon fibers presenting actual carbon fibers in a pseudo manner. In this case, the linear groove extends along the extending direction of the pseudo carbon fiber bundle. The linear groove is formed to be depressed from the reference plane of the carbon-toned irregular surface  12   a  along the depth direction (deepness direction). As used herein the reference plane is a plane on the rear surface side in the depth direction of the carbon-toned irregular surface  12   a , for example, a plane along the top portion  12   d  of the carbon-toned irregular surface  12   a . The depth of the linear groove is the distance between the reference plane and the bottom portion of the linear groove in the depth direction. A plurality of pseudo carbon fiber bundles include a pseudo carbon fiber bundle in which the length in the extending direction of the linear groove and the depth of the linear groove vary in a predetermined range. Here, it is assumed that the pseudo carbon fiber bundle is a carbon fiber bundle formed by bundling 3000 actual carbon fibers (called 3K carbon fiber bundle). In the unit pattern  12   c  that constitutes a weave of pseudo carbon fiber bundles, the length in the extending direction of the linear groove and the depth of the linear groove vary in a predetermined range. In the case of the above-described 3K pseudo carbon fiber bundle, the unit patterns  12   c  are formed such that the length in the long side direction is 4 mm and the length in the short side direction is 2 mm. In this case, each linear groove is formed such that the length in the extending direction of the linear groove is in the range of 1 mm to 4 mm and the depth in the depth direction of the linear groove is in the range of 0 μm to 3 μm at random. As used herein “at random” means that the length of the linear groove and the depth of the linear groove are changed arbitrarily in a predetermined range. 
     The pseudo carbon fiber bundle may have a plurality of linear protrusions (not illustrated) that constitute pseudo carbon fibers presenting actual carbon fibers in a pseudo manner. The linear protrusion extends along the extending direction of the pseudo carbon fiber bundle. The linear protrusion is formed to protrude from the reference plane of the carbon-toned irregular surface  12   a  along the depth direction (height direction). As used herein the reference plane is a plane on the front surface side in the depth direction of the carbon-toned irregular surface  12   a , that is, a plane along the top portion  12   g  of the carbon-toned irregular surface  12   a . The height of the linear protrusion is the distance between the reference plane and the top portion of the linear protrusion in the depth direction. The pseudo carbon fiber bundles include a pseudo carbon fiber bundle in which the length in the extending direction of the linear protrusion and the height of the linear protrusion vary in a predetermined range. In the present embodiment, it is assumed that the pseudo carbon fiber bundle is a carbon fiber bundle formed by bundling 3000 actual carbon fibers (called 3K carbon fiber bundle). In the unit pattern  12   f  that constitutes a weave of pseudo carbon fiber bundles, the length in the extending direction of the linear protrusion and the height of the linear protrusion vary in a predetermined range. In the case of the above-described 3K pseudo carbon fiber bundle, the unit patterns  12   f  are formed such that the length in the long side direction is 4 mm and the length in the short side direction is 2 mm. In this case, each linear protrusion is formed such that the length in the extending direction of the linear protrusion is in the range of 1 mm to 4 mm and the height in the depth direction of the linear protrusion is in the range of 0 μm to 3 μm at random. As used herein “at random” means that the length of the linear protrusion and the height of the linear protrusion are changed arbitrarily in a predetermined range. 
     In the foregoing description, the top portions  12   d ,  12   g ,  12   r , and  12   u  are formed to be an ellipse shape (for example, oval shape) when viewed from the viewer side. However, embodiments are not limited to this shape. 
     In the example described above, the top portions  12   d ,  12   g , l 2   r , and  12   u  are formed to be flat. However, embodiments are not limited thereto. For example, they may be formed to be a curved shape having a curvature smaller than that of a pair of curved portions  12   e ,  12   h ,  12   q , and  12   t.    
     In the example described above, the carbon-toned irregular surface  12   a  includes seven kinds of unit patterns  121   c  to  127   c  with different top portion inclinations D. However, embodiments are not limited thereto. At least two kinds of unit patterns  12   c ,  12   f ,  12   s , and  12   v  are included. 
     In the example described above, the top portion inclination D is an inclination of the long axis P 1  relative to the reference line Q. However, embodiments are not limited thereto. The top portion inclination D may be an inclination of the short axis P 2  along the short side direction of the top portion  12   d  relative to the reference line Q. When the top portion  12   d  is an oval, the long axis P 1  corresponds to the longer diameter of the oval and the short axis P 2  corresponds to the shorter diameter of the oval. 
     In the example described above, the carbon decorative panel  1  is applied to the dial plate  100  as a decorative part having the carbon-toned pattern M. However, embodiments are not limited thereto and may be applied to a decorative sheet for an instrument panel. 
     The dial plates  100  and  100 A described above include the carbon decorative panels  1  and  1 A, the AG print layer  13 , the design layer  16 , and the smoke layer  17 . However, embodiments are not limited thereto and may have any other configuration. 
     The body  10   a  of the clear decorations  10 ,  10 A,  10 B, and  10 C described above includes the substrate  11  and the clear layers  12 ,  12 A,  12 B, and  12 C formed as separated components by imprinting. However, embodiments are not limited thereto. The body  10   a  of the clear decorations  10 ,  10 A,  10 B, and  10 C may be formed, for example, such that the substrate  11  and the clear layers  12 ,  12 A,  12 B, and  12 C are integrally formed by resin injection molding. 
     The clear layers  12 ,  12 A,  12 B, and  12 C described above are formed on the substrate  11  by UV-curing imprinting. However, embodiments are not limited thereto. For example, thermal-curing imprinting may be used. 
     The dial plates  100  and  100 A described above include the AG print layer  13  as a low reflection layer. However, a member other than the AG print layer  13  may be used to form a low reflection layer. 
     The AG print layer  13 , the carbon color layer  14 , the light-blocking print layer  15 , the design layer  16 , and the smoke layer  17  are formed using a screen printer in the example above. However, embodiments are not limited thereto. For example, they may be formed using an inkjet printer. 
     The resin decorative part and the dial plate according to the present embodiment includes at least two kinds of unit patterns in which the top portion inclinations of the unit patterns are different from each other. This configuration can achieve the resemblance to the top portions of the projection and depression shape of an actual carbon member and appropriately ensure the texture of the carbon-toned decoration. 
     Although the invention has been described with respect to specific embodiments for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
