Beschreibung
Zusammenfassung:	A vibration actuator includes: a fixing body including a hollow case and a coil, a movable body that includes a magnet, and an elastic supporting part that supports the movable body such that the movable body is freely movable with respect to the fixing body in the hollow case. The hollow case restricts a movement range of the movable body in the case by opposite end surface portions that are disposed to face each other at a distance from each other in the vibration direction of the movable body, the hollow case includes one or more vent holes, and the vent holes are disposed in a portion of at least one end surface portion of the opposite end surface portions, the portion being free from interference by the movable body.
