A piezoelectric power generation apparatus that includes a first vibrating portion having a fixed end and a free end, a first weight portion bonded to the free end of the first vibrating portion, a second vibrating portion having a fixed end bonded to the first weight portion and a free end, and including a vibrating plate and a piezoelectric element provided on the vibrating plate. A second weight portion is bonded to the free end of the second weight portion. In a state where the piezoelectric power generation apparatus is arranged on a vibration surface and is still, a position of the free end of the first vibrating portion and a position of the fixed end of the second vibrating portion in an axial direction perpendicular to the vibration surface are different from each other. |
