摘要:
A cap member capable of alleviating degradation of reliability and improving fabrication yields is provided. The cap member has a cylindrical side wall portion, a top face portion closing one end of the side wall portion and having a light exit hole formed therein to allow extraction of laser light from a semiconductor laser chip; a light transmission window fitted to the top face portion to stop the light exit hole, and a flange portion arranged at the other end of the side wall portion and welded on the upper face of a stem on which the semiconductor laser chip is mounted. A groove portion is formed in an inner surface of the top face portion, and this groove portion makes part of the top face portion in a predetermined region less thick than the other part thereof.
