A linear vibration motor has a movable element including a magnet and a weight, and an elastic member are inserted into a frame. The frame supports the movable element so the movable element can freely slide axially; a coil fixed to the frame and drives the magnet axially; and an elastic member applying, to the movable element, an elastic force against the driving force of the magnet. The frame has a bottom surface plate with a bottom surface affixing the coil; an upper surface plate has an upper surface opposing the bottom surface; and a front surface plate facing the axially and supports the elastic member. The bottom surface plate has partial side surface portions that are respectively bent from both side edges of the bottom surface portion and in which an opening is formed in a central part of the partial side surface portions in the axial direction.
