Abstract
In a semiconductor laser device, a semiconductor laser element is so fixed to a base that a distance between a convex side of a warp of the semiconductor laser element and the base varies with the warp of the semiconductor laser element along a first direction corresponding to an extensional direction of a cavity while a wire bonding portion is provided around a portion of an electrode layer corresponding to the vicinity of a region where the distance is the largest.
