A vibration actuator includes: a movable body including a core around which a coil is wound in a state in which a tip part of the core is exposed; a fixed body including one or more magnets disposed away from and facing the tip part of the core; and a shaft part rotatably supporting the movable body on a side of a base end part of the core, and generates vibration by oscillation of the tip part of the core around the shaft part with respect to the one or more magnets by cooperation among the coil, the core and the one or more magnets.
