Abstract
A power generating element is provided that includes first and second plate-like structures, a pedestal that supports the first plate-like structure, and first and second piezoelectric elements that generate charges on the basis of the deflections of the two plate-like structures. A base end portion of the first plate-like structure is connected to the pedestal, and a direction from the base end portion toward the tip end portion of the first plate-like structure is a Y-axis positive direction. A base end portion of the second plate-like structure is connected to the tip end portion of the first plate-like structure via a connection body, and a direction from the base end portion toward the tip end portion of the second plate-like structure is a Y-axis negative direction. A frequency band of a half-value width of a resonance system formed on the basis of the flexibility of the second plate-like structure at least partially overlaps a frequency band of a half-value width of a resonance system formed on the basis of the flexibility of the first plate-like structure.
