Abstract
A semiconductor laser device includes a mounting board, a semiconductor laser element provided on the mounting board, and an optical member. The optical member is made of silicon having a first {110} plane, a first {100} plane that is adjacent to the first {110} plane, a second {110} plane, and a second {100} plane that is adjacent to the second {110} plane, with the second {100} plane being fixed on the mounting board, and the first {110} plane being covered by a reflective film to reflect laser light emitted from the semiconductor laser element.
