An optical head device includes a laser beam emitting element, a light receiving element, an optical system which guides an emitted light beam from the laser beam emitting element to the optical disk and guides the reflected light beam from the optical disk to the light receiving element, and a main body frame on which the laser beam emitting element, the light receiving element and the optical system are mounted. The main body frame is constructed of a metal frame and a resin frame. The optical system, the laser beam emitting element and the light receiving element are attached to the metal frame and the metal frame is attached to the resin frame.
