<p>An optical fiber unit for an optical fiber sensor improves the degree of freedom in setting a jig. The optical fiber unit includes an optical fiber cable, a shaft, and a head. The shaft includes a peripheral surface having a male thread, and a through-hole in which the optical fiber cable is inserted. The head is shaped in a polygonal prism including a plurality of sides and a bottom. The head includes a plurality of sides including a first side and a second side adjacent to each other. The shaft is connected to the bottom of the head. The head includes a space that communicates with the through-hole. The space is exposed at an opening formed in at least the first side and the second side among the plurality of sides. The opening includes a first opening portion formed in the first side, and a second opening portion formed in the second side. The first opening portion and the second opening portion communicate with each other.</p> |
