This power generation device is provided with: a fixing section (2); a beam section (4) wherein one end side is supported by the fixing section; a weight section (6), which is supported by the other end side of the beam section, and which is vibrated with the beam section; a stopper section (7) that regulates, by having the weight section in contact with the stopper section, movement of the weight section in the vibration direction; and a piezoelectric element (5), which is attached to the beam section, and which generates power by being deformed with deformation of the beam section. The weight section is provided with a magnet (9). The stopper section is provided with a coil (10) that is configured from a coil pattern formed on a printed board. The magnet and the coil are disposed facing each other. Power is generated at the coil with the vibration of the weight section that is provided with the magnet. |
