Abstract: Provided is a piezoelectric laminate element that outputs a fixed output voltage even in response to a static load for which an output voltage could not be obtained using a conventional piezoelectric element. A piezoelectric laminate body in which a plurality of piezoelectric polymer film layers consisting of film such as polylactic acid film that exhibits piezoelectricity in the planar direction are laminated is used as a piezoelectric laminate element. The piezoelectric laminate body is given a cylindrical shape, rounded rectangle shape, or other partially curved shape. The output voltage follows the increase and decrease of the applied load, and if a fixed load is continuously applied, a fixed output voltage is continuously output, and a piezoelectric laminate element is obtained that outputs a fixed output voltage even if a load is static.
