This invention provides an optical fiber head in which a lens can reliably be fixed to a case body by a simple configuration, and therefore the optical fiber head can easily be produced at low cost. The optical fiber head includes a light projecting fiber, a light projecting lens, and a case body accommodating and holding the light projecting fiber and the light projecting lens. A blocking unit in which an opening is formed, a light projecting lens inserting hole, and an optical fiber inserting hole are provided in the case body. The light projecting fiber is fixed to the case body while a leading end surface of the light projecting fiber abuts on a rear end surface of the light projecting lens, so that the light projecting lens is fixed to the case body by being sandwiched between the blocking unit and the light projecting fiber in an axial direction. |
