An object of the present invention is to provide a semiconductor laser device that has a simple structure that can easily be constructed, and can dissipate heat easily, and can improve its functionality and realize miniaturizing concurrently. The semiconductor laser device composes a metal plate 100 that is substantially the same as the bigger one of the widths of the silicon substrate 120 and the flexible sheet 130, a semiconductor laser element 110, a silicon substrate 120 into which a light detection circuit and a signal processing circuit are integrated, a flexible sheet 130, a wire 140 and an optical element 150. The flexible sheet 130 is divided into two on the metal plate 100, and the two divided flexible sheet 130 are positioned face to face sandwiching the silicon substrate 120.
