Abstract
A touch sensor that includes a pressure detection sensor and a position detection sensor. The pressure detection sensor and the position detection sensor are sequentially disposed from an operation surface side of the touch sensor. The position detection sensor includes a dielectric substrate, first position detecting electrodes on a first principal surface of the dielectric substrate, and second position detecting electrodes on a second principal surface of the dielectric substrate. The pressure detection sensor includes a piezoelectric film, a first piezoelectric detecting electrode on a first principal surface of the piezoelectric film, and a second piezoelectric detecting electrode on a second principal surface of the piezoelectric film. The first and second piezoelectric detecting electrodes are disposed so as to not overlap the first and second position detecting electrodes.
