Abstract
According to one embodiment of the present invention, a camera module includes: a movable element having first magnets which are formed at uniform intervals on the outer circumferential surface of a bobbin fixing a lens and second magnets which are arranged between the first magnets on the outer circumferential surface of the bobbin; a stator having first coil blocks which respectively face the first magnets, second magnets which respectively face the second magnets, and a housing which fixes the first coil blocks and the second magnets; an elastic member elastically supporting the movable element with respect to the stator; a base supporting the stator; and a case covering the housing and coupled to the base.
