Abstract

A semiconductor layer for supporting a diode chip of a semiconductor laser is formed to be higher than a semiconductor layer containing a current-conducting region, whereby stresses acting on the diode chip by mounting the diode chip are relieved to prevent degradation of performance and reduced life of the semiconductor laser.
