PROBLEM TO BE SOLVED: To provide a power generator that can reduce the generation limit flow rate of fluid excitation vibration and increase the power generation efficiency.SOLUTION: A power generator 1a has a frame-like support part 2, a cantilever part 3 which is disposed inside the support part 2 and has one end serving as a fixed end 31 to the support part 2 and the other end serving as a free end 32, and a flow passage 7 formed between the support part 2 and the cantilever part 3. In the power generator 1a, at least a part of the cantilever part 3 is configured by a flexible beam part 4. The power generator 1a has a piezoelectric converter 5 for generating an AC voltage according to vibration of the cantilever part 3 provided to a first surface 41 in the thickness direction of the beam part 4, and a reinforcing part 6 formed along the axial direction of the beam part 4 on a second surface 42 in the thickness direction of the beam part 4. The cantilever part 3 is warped to be located out of a space 29 in which the free end 32 is surrounded by an inner surface 200 of the support part 2. |
