Abstract
An electrostatic capacitance type touch sensor is provided. The touch sensor includes 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 first linear wires being arranged parallel to each other at a predetermined interval, and the second linear wires being arranged parallel to each other at a predetermined interval and intersecting with the first linear wires. A separation portion is provided to the first linear wires 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. The shape of a gap between the sensor portion and the dummy sensor portion located next to each other is improved not being formed into a band-like shape surrounded by two parallel conductive linear wires, and a boundary between the sensor portion and the dummy sensor portion located next to each other can be less-visible thereby improving the appearance, and the capacitance between the sensor portion and the dummy sensor portion located next to each other is reduced, thereby improving the accuracy of detecting a touch by adjusting the sensitivity.
