Abstract:
A camera module 100 includes a movable section 10 that includes a lens 11, a fixed section 30 having a hollow space extending in the optical axis direction of the lens 11, and an elastic body 40 that elastically supports the movable section 10 and the fixed section 30, an imaging element 3 that is fixed to the fixed section 30 and has a light-receiving surface perpendicular to the optical axis of the lens 11, a plurality of magnets 31a, 31b, 31c, and 31d arranged along the fixed section 30, and a coil section 22 provided in the movable section 10. The elastic body 40 includes an upper spring 41a and a lower spring 41b, which support the fixed section 30 between adjacent ones of the magnets 31a, 31b, 31c, and 31d along the arrangement direction of these magnets on a plane perpendicular to the optical axis of the lens 11. With this configuration, it is possible to provide a camera module with an automatic focusing control function, whose thickness can be reduced remarkably.
