Abstract
A piezoelectric power generator that includes a piezoelectric laminate in which a plurality of rectangular-shaped piezoelectric elements each having electrodes formed on a substrate are connected at both ends thereof to each other, and in which a portion other than connection portions is capable of vibrating. In the piezoelectric laminate, a portion of the element at the uppermost layer is a fixed portion, and a weight is mounted to the element (free end) at the lowermost layer. Each piezoelectric element is decreased in rigidity from the element at the uppermost layer toward the element at the lowermost layer.
