摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic driving device capable of oscillating a movable member stably and effectively even at a high temperature without using a permanent magnet.SOLUTION: The electromagnetic driving device comprises: a lens holder 12 that is a movable member; and a case 11 that functions as a fixing member supporting the lens holder 12 in such a manner to allow the lens holder 12 to be oscillated. A driving plate-shaped repulsive member 15 made of a nonmagnetic conductive material is mounted to the case 11 and a driving coil 14 is attached to the lens holder 12 in such a way that the axial direction of the coil is in the thickness direction of the driving repulsive member 15, or the driving coil 14 is attached to the case 11 and the driving repulsive member 15 is mounted to the lens holder 12. An AC current is applied to the driving coil 14 to generate an eddy current in the driving repulsive member 15, thereby generating a repulsive force caused by the eddy current between the driving coil 14 and the driving repulsive member 15. The repulsive force moves the lens holder 12 in the axial direction of the lens holder 12.
