PURPOSE:To miniaturize a semiconductor laser device while simplifying the adjusting mechanism of the plane of polarization. CONSTITUTION:A flat surface 16 parallel with the minor-axis direction of the output pattern of an illuminant 10 is formed M a package 15, in which the illuminant 15 is housed. The flat surface 16 can be used as the attitude reference plane of the package 15, and adjustment is facilitated. |
