英文摘要	PURPOSE:To improve coupling efficiency, and stably operate a laser without affection of reflected light by coupling the outputting surface of a semiconductor laser and the end surface of an optical waveguide, via optical adhesive agent. CONSTITUTION:By using transparent optical adhesive agent such as ultraviolet ray curing adhesive agent and epoxy adhesive agent, the following are fixed; the end surface 8 of the side, of an optical waveguide member 5, which corresponds with a semiconductor laser 3, the end surface 9 of a step part of a heat sink 1, and the outputting surface 10 of the semiconductor laser 3. The optical waveguide member 5 is constituted of a substrate 6 and an optical waveguide 7 formed thereon, and the semiconductor laser 3 is constituted of a high reflectivity coating layer 13 and an active layer 14. Since the optical adhesive agent 12 is positioned at the outputting surface 10 side of the laser 3, the reflectivity of the outputting surface 10 side is decreased, and the total reflectivity can be increased by a coating layer 13. The reflectivity of the adhesive agent 12 is smaller than that of the air, so that the laser light effectively makes an incidence into the waveguide 7.
