Abstract:
1. A semiconductor laser comprising: a base having a planar shape that is substantially circular; two leads that are respectively fixed to said base through insulating material; a heat sink that is provided on one surface side of said base, said heat sink having a surface with a width wider than a distance between said two leads, said surface being parallel to a plane formed by said two leads and perpendicular to said base; and a laser chip that is fixedly attached to said surface of said heat sink, wherein said two leads are provided to be substantially parallel to one diameter of said base and remote by a specified distance from said one diameter, and wherein said heat sink is fixedly provided to said base such that said heat sink does not contact the insulating material for fixing said two leads and such that an emitting portion of said laser chip is located in center of said base.
