Vibration actuator and vibration presentation device

A vibration actuator configured to apply a vibration to a connected vibration presentation part, the vibration actuator comprising:

• a fixing body including a base part composed of a non-magnetic substance, and a magnetic suction force generation part provided at a core on which a coil is wound, the base part having a planar shape;
• a movable body including a connecting part connectable to the vibration presentation part, and a suction part composed of a magnetic material configured to be suctioned by the magnetic suction force generation part through energization to the coil, the movable body having a plate-shape and disposed on the base part;
• and
• a plurality of elastic support parts configured to support the movable body with respect to the fixing body such that the movable body is sandwiched from a vibration direction along a surface of the base part and that the movable body is movable in the vibration direction,
• wherein the suction part is disposed in a vicinity of a magnetic pole of the core of the magnetic suction force generation part with an air gap between the suction part and the magnetic pole in the vibration direction, and the suction part is disposed at a center portion in the vibration direction of the movable body supported by the plurality of elastic support parts.
