Abstract
Provided is a power generator. The power generator includes two magnetostrictive rodsarranged side by side and formed on a magnetostrictive material, coilsrespectively wound around the magnetostrictive rodsand a beam memberhaving a function of generating stress in the two magnetostrictive rods. The power generatoris configured so that elastic energy stored in the beam memberis larger than elastic energy stored in each of the magnetostrictive rodswhen tip end portions of the two magnetostrictive rodsand the beam memberare displaced with respect to base end portions of the two magnetostrictive rodsand the beam memberto deform the two magnetostrictive rodsand the beam member
