PROBLEM TO BE SOLVED: To provide a technique that can effectively prevent tangling of optical fibers wired in a frame and that also can improve the workability in wiring and taking out optical fibers. SOLUTION: The optical fiber unit 1 is characterized by the formation of a binding fixing part 5 that is bendable and deformable, by using optical fibers 4 in which both ends in the longitudinal direction are terminated so as to be connectable with optical connectors 3 and by fixedly binding the center part of the plural optical fibers 4 in the longitudinal direction using a flexible binder 2.
