Abstract

PURPOSE: To increase the accuracy for detection position, by providing a plurality of sectioned detection electrodes on the upper and lower surface of the piezoelectric substance, in the position detection element using piezoelectric body.
CONSTITUTION: The detection electrode 1 is sectioned into a plurality of parts and placed on the upper and lower surface of the piezoelectric substrate 2. Further, the dielectric substrate 4 is formed by covering the detection electrode 1 at the lower surface and the ground electrode 3 is placed at the surface.
