Abstract:
A touch panel include a cover member, a drive electrode, a pressure detecting electrode, and a position detecting electrode. The pressure detecting electrode and the position detecting electrode are alternately arranged in a first direction. The pressure detecting electrode includes a plurality of pressure detecting sections, arranged side by side in a second direction orthogonal to the first direction, that each independently detect a pressure. The position detecting electrode includes a plurality of position detecting sections, arranged side by side in the second direction, that each independently detect a touched position. The area of a pressure detecting section is larger than the area of a position detecting section.
