Optical scanning actuator

An optical scanning actuator that performs scanning with light emitted from an optical element, the optical scanning actuator comprising:

• a movable unit that supports the optical element and is movable together with the optical element;
• a plurality of leaf springs which has a thin plate shape and of which one end portion in a longitudinal direction is fixed and another end portion in the longitudinal direction is attached to the movable unit;
• and
• an electromagnetic driving unit that includes a magnet that generates a magnetic flux, a yoke that is laminated in part on the magnet and forms a closed magnetic circuit together with the magnet, and a coil that is held by the movable unit, is positioned in a gap between the magnet and the yoke, includes an opening plane being substantially orthogonal to a laminating direction of the magnet and the yoke, and drives the movable unit by an electromagnetic force applied to the coil.
