PROBLEM TO BE SOLVED: To provide an optical fiber sensor head capable of easily slightly adjusting the direction of light and moreover having excellent assemblability. SOLUTION: A holder 14 is fitted into the tip end of the sleeve 13 housing the optical fiber 10 of this optical fiber sensor head, and a window part 17 opened to the side and the reflecting body 20 reflecting light emitted from the tip end surface of the optical fiber 10 toward the window part 17 are provided in the holder 14. And the reflecting body 20 is moved together with the holder 14 to execute an inclination adjustment. Hereupon, since the holder 14 is relatively larger compared to the reflecting body 20, the inclination adjustment is easily executed. |
