The electrostatic capacity coupling type touch panel includes X electrodes (XP) and Y electrodes (YP) which intersect each other via a first insulating layer, and a plurality of Z electrodes in floating states to each other via a second insulating layer. For the second insulating layer, a material which changes in thickness by pressing of touch is used. The Z electrode is disposed so as to overlap both an X electrode and a Y electrode which are adjacent to each other. In a pad part of the X electrode, an area is larger toward the center of the X electrode and an area is smaller toward the center of the adjacent X electrode. Therefore, the nonconductive input means can be used, and highly accurate position detection is realized with a small number of electrodes even when a touch area is small.
