A power generator 1 includes at least two magnetostrictive elements 10 each including a magnetostrictive rod through which lines of magnetic force pass in an axial direction thereof and a coil 3 wound around the magnetostrictive rod 2; and a beam member 83 for connecting one end portions of the magnetostrictive elements 10 with each other and the other end portions of the magnetostrictive elements 10 with each other. Further, the power generator 1 includes a permanent magnet 6 for generating the lines of magnetic force passing through the magnetostrictive rods 2. The permanent magnet 6 is provided so that a magnetization of the permanent magnet 6 differs from an arrangement direction in which the magnetostrictive elements 10 are arranged side by side.
