Abstract
Provided is a semiconductor laser device capable of being easily accurately mounted on the mounting portion of an optical pickup device. A semiconductor laser element is mounted on a side surface of a heat sink of a base via a submount, and a light-receiving element is mounted on an upper surface of the heat sink. A stem constructed by arranging two resin lead blocks on both sides of the base is covered with a cap, and a hologram element is arranged in an opening provided at an upper surface of the cap. Skirt portions constructed by partially extending peripheral surfaces of a long side of the cap are inserted into recess portions of the stem, and tip portions of projections projecting in the recess portions and inner surfaces of the skirt portions are joined to each other by resistance welding.
