    摘要: An actuator has a magnet moved together with a moving lens frame, an SMA wire capable of extending and contracting in a moving direction I of the moving lens frame with execution or non-execution of energization thereof, a fixing member made of a magnetic material attached to a distal end of the SMA wire, a pressing spring which urges the fixing member toward the magnet along the moving direction I, and a stopper member and a stopper portion which limits the movement of the magnet along the moving direction I at a first position or a second position.
