A semiconductor laser module comprising a semiconductor laser, a first lens that converts light emitted from the semiconductor laser into parallel light, and a second lens that focuses the parallel light into a polarization-maintaining fiber. A polarizing plate is rotatably disposed between the first and second lenses at the optical axis thereof, and by rotating this polarizing plate, the polarization plane of the semiconductor laser beam and the polarization plane preservation direction of the polarization preservation fiber are changed. A semiconductor laser module characterized in that it is capable of correcting minute angular errors in the direction of rotation.
