wherein, in the back layer ( 23 ) of the fixing region ( 52 b ), the first fiber ( 11 ) and the second fiber ( 12 ) are located in the Y direction, and the sixth fiber ( 16 ) is located in parallel to the Z direction, the sixth fiber ( 16 ) being woven with the first fiber ( 11 ) and the second fiber ( 12 ),
wherein, in the intermediate layer ( 22 ) of the fixing region ( 52 b ), the seventh fiber ( 17 ) being an optical fiber is located in parallel to the Z direction,
wherein the seventh fiber ( 17 ) being an optical fiber is interposed and fixed in a space between the surface layer ( 21 ) and the back layer ( 23 ) and is not woven into another fiber,
wherein in the light emitting region ( 52 a ), the decorative region ( 51 a ) and at left and right sides of the light emitting region ( 52 a ), the third fiber ( 13 ) and the fourth fiber ( 15 ) are not present, and
wherein the surface layer ( 21 ) of the first decorative region ( 51 a ) is the same as the surface layer ( 21 ) of the second decorative region ( 51 b ), and the first fiber ( 11 ) and a second fiber ( 12 ) are located in a Y direction, and a sixth fiber ( 16 ) is located in parallel to a Z direction, the sixth fiber ( 16 ) being woven with the first fiber ( 11 ) and the second fiber ( 12 ),
wherein, in the back layer ( 23 ) of the first decorative region ( 51 a ), the third fiber ( 13 ) and the fourth fiber ( 14 ) are not present, and the fifth fiber ( 15 ) is located in parallel to the Z direction, and
wherein, in the intermediate layer ( 22 ) of the first decorative region ( 51 a ), the seventh fiber ( 17 ) is not present.
