ABSTRACT:
The present invention provides a semiconductor laser device which comprises a metallic stem, a cap mounted to one surface of the stem, a mounting block arranged to project from the one surface of the stem into the cap, and a semiconductor laser chip by the mounting block. The stem comprises a first stem member and a second member joined to the first stem member in lamination thereto. The first stem member is formed with a cutting line partially surrounding a portion of the first stem member. The mounting block is provided by bending the partially surrounded portion into the cap to leave a corresponding perforation in the first stem member.
