PROBLEM TO BE SOLVED: To provide a power generation apparatus configured to be installed on a vehicle and generate power by vibrations of the vehicle which efficiently generates power in many frequency bands.SOLUTION: A power generation apparatus 1 includes a fixing member 5 adapted to be mounted on a vehicle, a plurality of masses (31, 32, 33), and as many displacement members (21, 22, 23) with piezoelectric elements (21b, 22b, 23b) as the plurality of masses (31, 32, 33). One displacement member 21 of the plurality of displacement members (21, 22, 23) couples the fixing member 5 and one mass 31 of the plurality of masses (31, 32, 33), and the other displacement members (22, 23) of the plurality of displacement members (21, 22, 23) couple the plurality of masses (31, 32, 33) in series. |
