Abstract
In this semiconductor laser device, a semiconductor laser element is so fixed to a base that a distance between a convex side of a warp thereof and the base varies with the warp of the semiconductor laser element at least along a first direction corresponding to an extensional direction of a cavity or a second direction, while a wire bonding portion is provided around a portion of an electrode layer corresponding to the vicinity of a region where the distance between the convex side of the warp of the semiconductor laser element in at least either the first direction or the second direction of the semiconductor laser element and the base is substantially the smallest.
