Vibration actuator and electronic apparatus

The vibration actuator includes: a fixed body including a coil; a movable body including a magnet disposed radially inward of the coil so as to be relatively movable in a vibration direction orthogonal to the radial direction of the coil; and an elastic support part which supports the movable body in a manner that the movable body can move freely relative to the fixed body, in the vibration actuator, the movable body vibrates relative to the fixed body through cooperation of a coil which is supplied with power and a magnet, and the elastic support part is provided with: an outer peripheral part which is fixed on the fixed body; an inner peripheral section that is disposed further toward the inside in the radial direction than the outer peripheral section and that is fixed to the movable body; the vibration actuator includes an outer peripheral portion, an inner peripheral portion, and a deformation arm portion disposed between the outer peripheral portion and the inner peripheral portion, connecting the outer
