ABSTRACT:
A semiconductor laser device includes a package having a front surface, a rear surface and an outer peripheral surface; a semiconductor laser element and a light receiving element provided on the front surface; a plurality of leads arranged in spaced relation on the front surface as extending outward from the package; and an optical element supported above the front surface with its optical axis perpendicular to the front surface for guiding a laser beam emitted from the semiconductor laser element toward an object and guiding light reflected on the object to the light receiving element; wherein the outer peripheral surface is configured so as to be fitted in a cylindrical hole having an axis parallel to the optical axis of the optical element, and has a recess extending from the front surface to the rear surface, and the leads are bent as extending from the front surface and passing through the recess with distal portions thereof extending along the optical axis of the optical element and with proximal ends thereof electrically connected to the semiconductor laser element and the light receiving element.
