Title:
TOUCH SENSOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2016081582
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a touch sensor which has uniform and high pressing operability and responsibility on an operation surface while being further thinned.SOLUTION: According to the present invention, a touch sensor 1 detecting a pressing state to a pressing direction on a predetermined operation screen, comprises: a first electrode layer 2 and a second electrode layer 4 that detect the variation of the electrostatic capacitance; and a displacement layer 3 that is disposed between the first electrode layer 2 and the second electrode layer 4 and can displace a gap between the first electrode layer 2 and the second electrode layer 4 by pressing to the operation surface. The displacement layer 3 is constructed by dispersing a polymer-type silane coupling agent 11 into a rubber-like elasticity member 10 and has at least a plurality of column parts 31 contractable in a pressing direction. In the touch sensor 1, the column parts 31 and a layer of at least one of the first electrode layer 2 and the second electrode layer 4 are integrally joined.SELECTED DRAWING: Figure 1
