Touch sensor wiring body, touch sensor wiring substrate, and touch sensor

Abstract

A touch sensor wiring body (3) equipped with a first resin layer (31), a first conductor layer (32) having a first conductor line (322) and provided on the first resin layer (31), a second resin layer (33) for covering the first conductor layer (32), and a second conductor layer (34) having a second conductor line (342) and provided on the first conductor layer (32) with the second resin layer (33) interposed therebetween, wherein the first and second conductor layers (32, 34) are electrically insulated by the second resin layer (33), and satisfy formula (1). D1<D2 (1) Herein, D1 represents the thickness of the first resin layer (31) in a first region corresponding to the first conductor line (322) in a first prescribed cross-section that transects the touch sensor wiring body (3) along the second conductor line (342), while D2 represents the thickness of the second resin layer (33) in the first region of the first prescribed cross-section.

AI Technical Summary

Problems solved by technology

However, in the touch sensor of the above-mentioned technology, if the thickness of the transparent polymer layer between the conductive layer of the first layer and the conductive layer of the second layer of the wiring body is thin, the following disadvantages will occur. In the case of body contact, the released lines of electric force are also closed between the electrodes, making it difficult to react to the contact body

As a result, deterioration of electrical characteristics such as a decrease in sensitivity is caused, and further, it may not be able to function as a wiring body having a double conductive layer.

On the other hand, if the distance between the two-layer conductive layers is increased, the above-mentioned deterioration of the electrical characteristics is less likely to occur, but the film thickness becomes thicker, which hinders the reduction in weight and thickness.
