Abstract
The present invention aims to provide an electromagnetic driving device capable of efficiently driving swinging coils and being more miniaturized. A driving coil wound around the Z axis taken as a direction of the optical axis of a lens is mounted on a lens support. Magnets are mounted in an inner side box body for supporting the lens support to be capable of moving in the direction of Z axis. The swinging coils are mounted in an outer side box body for supporting the inner side box body to be capable of swinging in the direction orthogonal to the Z axis. The swinging coils includes a first to a fourth coils wound around axes orthogonal to the Z axis. The magnets include a plurality of magnet pieces configured opposite to the swinging coils.
