    • PURPOSE: A semiconductor laser device having a dielectric reflective film on an optical exit face is provided to form easily a desired refractive index by using different refractive indexes of the dielectric films. CONSTITUTION: A semiconductor laser device includes a reflective film. The reflective film includes a multilayer dielectric film.
