A touch sensor that includes a pressure detection sensor and a position detection sensor. The pressure detection sensor includes a piezoelectric film, a first piezoelectricity detecting electrode adjacent a first principal surface of the piezoelectric film, and a second piezoelectricity detecting electrode adjacent a second principal surface of the piezoelectric film. The position detection sensor includes a dielectric substrate, a plurality of first position detecting electrodes adjacent a first principal surface of the dielectric substrate, and a plurality of second position detecting electrodes adjacent a second principal surface of the dielectric substrate. In the pressure detection sensor, the second piezoelectricity detecting electrode includes an electrode non-forming section in a region where the first position detecting electrode and the second position detecting electrode overlap each other.
