Abstract
A detection electrode and an X-driving electrode (first driving electrode) are stacked through a sensor side insulating layer, at the side of a sensor portion of a film base material, and a Y-driving electrode (second driving electrode) is formed on the same forming surface as the detection electrode. The X-driving electrode is formed of a first conductive layer, the detection electrode and the Y-driving electrode are formed in a stacked structure of a second conductive layer having a resistance lower than the first conductive layer and a third conductive layer having a resistance higher than the first conductive layer and the second conductive layer.
