A power generator 100 of the present invention is configured to be used in a state that the power generator 100 is fixedly attached to a vibrating body formed of a magnetic material. The power generator 100 includes a main unit 1 having a power generating unit 10 configured to generate electric power by utilizing vibration and a base 23 having one surface on which the power generating unit 10 is supported and another surface 230 opposed to the one surface; and at least one permanent magnet 911 disposed on the side of the other surface 230 of the base 23 in a state that the permanent magnet 911 can be displaced or deformed in a thickness direction of the base 23. When the main unit 1 is fixedly attached to the vibrating body through an attachment 9 including the permanent magnet 911, the main unit 1 is configured to generate the electric power by utilizing vibration of the vibrating body.
