Abstract: A magnetostriction-type vibration powered generator including a power generating section and a frame joined to the power generating section. The power generating section includes a diaphragm formed of non-magnetic material and disposed at a first end of the power generating section, a magnetostriction element disposed at a second end of the power generating section; and a coil wrapped around the magnetostriction element along the longitudinal direction. The frame includes a frame body formed of a magnetic material and joined to a second end of the power generating section. A magnet is provided on the frame body so as to face the magnetostriction element of the power generating section.
