Abstract
A power generation element includes: a first nnagnetostrictive rod made of a nnagnetostrictive material; a rigid rod made of a magnetic material and disposed in parallel with the first nnagnetostrictive rod, the magnetic material having rigidity and a shape that enable uniform application of a compression or tensile force to the first nnagnetostrictive rod; a first coil wound around the first nnagnetostrictive rod; and two connecting yokes, each of which is provided at one end of each of the first nnagnetostrictive rod and the rigid rod to connect the first nnagnetostrictive rod and the rigid rod; wherein the power generation element generates power through expansion or contraction of the first nnagnetostrictive rod due to vibration in a direction perpendicular to a longitudinal axis of the first nnagnetostrictive rod.
