Claim:
1. A touch sensor comprising: a pressure detection sensor that includes a piezoelectric film having a first surface and a second surface, the first surface and the second surface being orthogonal to a thickness direction of the piezoelectric film, a first piezoelectricity detecting electrode adjacent the first surface, and a second piezoelectricity detecting electrode adjacent the second surface; and an electrostatic position detection sensor that includes a dielectric substrate having a third surface and a fourth surface, the third surface and the fourth surface being orthogonal to a thickness direction of the dielectric substrate, a first position detecting electrode adjacent the third surface, and a second position detecting electrode adjacent the fourth surface, wherein the pressure detection sensor and the electrostatic position detection sensor are arranged such that the first surface and the second surface are parallel to the third surface and the fourth surface, and the second piezoelectricity detecting electrode includes an electrode non-forming section at a position where the first position detecting electrode and the second position detecting electrode overlap each other when the pressure detection sensor and the electrostatic position detection sensor are arranged such that the first surface and the second surface are parallel to the third surface and the fourth surface.
