Abstract: A semiconductor laser module includes a semiconductor laser that outputs laser light; an optical fiber that guides the laser light; a lens that couples the laser light, which is output from the semiconductor laser, with the optical fiber; a base that is substantially tabular in shape and that has the semiconductor laser, the optical fiber, and the lens fixed thereon either directly or indirectly; and a housing which houses the base and fixes the base either directly or indirectly. Among faces of the base, a face on a side that is fixed either directly or indirectly to the housing includes a junction plane that is joined to the housing either directly or indirectly, and a detachment plane that is detached to remain unfixed from the housing.
