Abstract
Provided is a power generator 1. The power generator includes two magnetostrictive rods 2 arranged side by side and formed of a magnetostrictive material; coils 3 wound around the magnetostrictive rods 2; and a beam member 73 having a function of generating stress in each of the magnetostrictive rods 2. Each of the magnetostrictive rods 2 has one end portion and the other end portion. The power generator 1 is configured to generate a voltage in the coils 3 due to variation of density of lines of magnetic force when the other end portion of each of the magnetostrictive rods 2 is displaced with respect to the one end portion of each of the magnetostrictive rods 2 in a direction substantially perpendicular to an axial direction of the magnetostrictive rods 2 to expand and contract each of the magnetostrictive rods 2. Further, in the power generator 1, a loss coefficient of a constituent material of the beam member 73 is smaller than a loss coefficient of the magnetostrictive material of each of the magnetostrictive rods 2.
