A touch panel includes X electrodes and Y electrodes disposed on a support substrate in such a manner that each of the Y electrodes intersects the X electrodes, X floating electrodes laminated on a first insulating layer at places opposed to the X electrodes, Y floating electrodes laminated on the first insulating layer at places opposed to the Y electrodes, and a second insulating layer covering the X floating electrodes and the Y floating electrodes. The area of X electrodes is smaller than the area of X floating electrodes and the area of Y electrodes is smaller than the area of Y floating electrodes in a unit lattice region of a lattice formed of the X electrodes and the Y electrodes. A mutual capacitance generated between an X electrode and a Y electrode decreases when a surface of the second insulating layer is touched by a pointer.
