Claim:
1. A semiconductor laser module comprising: a semiconductor laser element configured to output a laser light; an optical fiber comprising a core portion and a cladding portion formed at an outer periphery of the core portion, the laser light being made incident into an end of the optical fiber, the optical fiber being configured to guide the laser light to outside the semiconductor laser module; an optical component being disposed at an outer periphery of the optical fiber and being configured to fix the optical fiber; a first-fixing agent configured to fasten the optical component and the optical fiber; a light-absorbing element being disposed at an outer periphery of the optical component and being configured to fix the optical component; a first light-blocking portion disposed between an end, into which the laser light is incident, of the optical fiber and the optical component, the first light-blocking portion including an aperture through which the optical fiber passes; and a housing configured to accommodate therein the semiconductor laser element, an end, at a side into which the laser light is incident, of the optical fiber, and the first light-blocking portion, wherein the optical component has an optical transmittance at a wavelength of the laser light, and the light-absorbing element has an optical absorptivity at a wavelength of the laser light.
