PROBLEM TO BE SOLVED: To provide a vibration force power generating apparatus that improves power generation efficiency of piezoelectric elements.SOLUTION: A vibration force power generating apparatus 1 generates power by pressure fluctuations caused by vibration, and includes: piezoelectric elements 10; and vibration plates 20 that transmit vibration to the respective piezoelectric elements 10. Each piezoelectric element 10 is arranged at least in a side surface of each vibration plate 20. In a portion, corresponding to the piezoelectric element 10, of a side surface of each vibration plate 20 opposite to the side surface in which the piezoelectric element 10 is provided, a cutout portion 21 is formed so as to fall within a range of the portion of the side surface corresponding to the piezoelectric element 10. The cutout portion 21 is not formed in portions of the side surface other than the portion corresponding to the piezoelectric element 10. |
