This invention provides a semiconductor laser device and method of manufacture with a small interval between light emitting points of laser lights. A first light emitting element having a semiconductor substrate and a laser oscillation section, and a second light emitting element having a laser oscillation section, are brought together with a ridged waveguide of the laser oscillation section facing the ridged waveguide of the laser oscillation section, and then bonded together by virtue of SOGs having a small thickness. A conductive wiring layer electrically connected with an ohmic electrode layer on the ridged waveguide, and a wiring layer electrically connected with an ohmic electrode layer on the ridged waveguide, are arranged to extend until the insulating layer on the semiconductor substrate. Further, the ohmic electrodes and are formed on the bottom surface of the semiconductor substrate and the top surface of the laser oscillation section, respectively.
