PURPOSE:To simplify a supplying mechanism by combining a mount, a lead frame, a stem base and a cap, and resin-sealing a rear surface of the stem base. CONSTITUTION:A laser pellet 7 and a photodiode pellet 8 are respectively mounted on mounts 2, 4, bonded to wires 9 via leads 3, 5, and a lead frame having the leads 3, 5 is inserted into a stem base 10 aligned in a ribbon state to be welded. Then, caps aligned in a ribbon state are sealed in the welded base 10. Thereafter, a rear surface of the base 10 is resin-sealed by molding to complete assembled products aligned in a ribbon state. Thus, when an assembling step is automated, product supplying mechanisms becomes one frame from individual ones, thereby simplifying the mechanisms. |
