Beschreibung
Zusammenfassung:	Provided is a vibration actuator that includes: a fixing part including a coil, and a core around which the coil is wound, the core including both ends projecting from the coil; a movable part disposed adjacent and opposite to the both ends of the core with a gap provided therebetween in a direction crossing with a winding axis of the coil, the movable part including a yoke formed of a magnetic material, the movable part being fixable to an operation contact surface part that is operated by contact; and a plate-shaped elastic part fixed between the movable part and the fixing part, the plate-shaped elastic part including an elastically deformable bellows-shaped part, the plate-shaped elastic part elastically supporting the movable part to be movable with respect to the fixing part in a direction opposite to at least one of the both ends.
