Abstract
A piezoelectric sensor includes: a piezoelectric sheet which is stretched in a uniaxial direction; an electrode which detects electric charges generated in the piezoelectric sheet; and an optical compensation layer which includes a slow axis stacked on at least one side of the piezoelectric sheet and intersects the uniaxial direction, and optically compensates for a phase difference produced when the piezoelectric sheet is stretched in the uniaxial direction.
