Patent ID: 8842093

Claim:
A touch sensor comprising: a substrate: and a grid pattern formed on a surface of the substrate by a plurality of first linear wires and a plurality of second linear wires, the grid pattern being formed integrally by a non-translucent conductive film, wherein the first linear wires are arranged parallel to each other at a predetermined interval, and the second linear wires are arranged parallel to each other at a predetermined interval and intersecting with the first linear wires, and a separation portion is provided to the first linear wires and the second linear wires by cutting a portion of the first and the second linear wires to form a sensor portion and a dummy sensor portion which are located next to each other and electrically separated from each other, wherein a gap between the adjacent sensor portion and the dummy portion is formed into a non-band-like shape, wherein a leading wire which is a portion of one of the first linear wire and the second linear wire constituting the sensor portion in the grid is arranged to extend out of the dummy sensor portion through the separation portion of another one of the first linear wire and the second linear wire constituting the dummy sensor portion, so that, at a gap between the dummy sensor portion and the leading wire extending parallel to said one of the first linear wire and the second linear wire constituting the sensor portion, an end of said another one of the first linear wire and the second linear wire constituting the dummy sensor portion is located adjacent to the leading wire across the separation portion.
