A vibration actuator includes: a movable element having a magnet that is supported to be rotatable around a shaft, a weight supported to be rotatable together with the magnet, and an elastic supporting member wherein a rotation of the magnet and the weight is supported elastically; a coil that is supplied with an AC current at a frequency that is equal to a resonant frequency of the movable element; and a magnetic pole member that causes the movable element to undergo reciprocating a rotational vibration around the shaft through applying rotational torques in different directions alternatingly to the magnet by changing magnetic poles through the AC current that is applied to the coil.
