To improve the efficiency of a linear vibration actuator, to miniaturize it to the utmost and to restrain heat generation thereof.

A magnet 24 is radially disposed on a surface of a shaft 22 of an actuator movable element 20 and the axial length of the actuator is reduced. In a stator 40, teeth 48 are additionally formed at a tip of a core material of an electromagnet 46. They are respectively formed into a permendur along with an electromagnetic steel plate formed of a laminate sheet, and the laminate direction of the laminate sheet is so arranged as to increase electromagnetic density. Generation of an eddy current is restrained by forming the core material and the teeth into a layered product, power consumption can be reduced by 40% as an effect of enhancing magnetic force, and the miniaturization of a device can be accomplished.
