An optical head for recording and reproducing information on an optical disk includes a box-like cover carrying thereon a semiconductor laser unit and a detector, and a substantially planar base on which various optical components are bonded, the base being made of the same material as the box-like cover and secured to the box-like cover to close an open end of the latter. By the use of the planar base, the optical components and the base can be bonded efficiently with utmost ease.
