Abstract
A camera module includes a housing defining an internal space; a reflection module disposed in the internal space and including a reflective member and a holder movably supported by an inner wall of the housing; and a lens module provided in the internal space, and including lenses aligned in an optical axis direction so that light reflected by the reflective member is incident to the lenses. The lens module includes lens barrels accommodating the lenses, and the plurality of lens barrels move in an approximate optical axis direction in the internal space while being supported by ball bearings. At least two of the lens barrels share a guide groove to guide movements of the ball bearings.
