Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser device with a semiconductor laser element for light pickup having an excellent 3-beam return light countermeasure, having large mass productivity and using a 3 beam method having high accuracy, and its manufacturing method. SOLUTION: In the semiconductor laser device containing one ore more of LD chips 101 used for light pickup using the 3 beam method and mounting the LD chips on a metallic stem 108 through a sub-mount 102, the side face of the sub-mount just under the laser-beam outgoing side faces of the LD chips is arranged while being inclined (a slope 111) so as to form an angle θ from 3 deg. to 30 deg. to the laser-beam outgoing side face. The sub-mounts used in this case are mass-produced by cutting sub-mount substrates by dicing. When 3-beam return light is returned to the sub-mount side, reflected light is reflected so as not to be mixed with an optical system on the sub-mount side face, on which the LD chips are loaded, and the possibility of the causing of a tracking error is reduced remarkably.
