Abstract
A method of manufacturing a power generation element includes a first step of disposing a support unit that supports a vibration unit in one end portion of the vibration unit in one direction, and disposing a weight unit in the other end portion of the vibration unit in the one direction in a substrate including the vibration unit capable of vibrating, a second step of disposing a piezoelectric unit that generates power due to vibration in a portion of the vibration unit on an opposite side from the support unit side in a thickness direction of the substrate after the support unit and the weight unit are disposed in the vibration unit, and a third step of extracting a power generation element from the substrate by cutting an outer edge of the vibration unit in the thickness direction of the substrate after the piezoelectric unit is disposed in the vibration unit.
