PROBLEM TO BE SOLVED: To improve the workability of branch working after the midway of working by unitizing a optical fiber wire and eliminating transmission loss due to bunching, without bunching in a single core type slot cable structure. SOLUTION: In the optical fiber unit, the three or more wires f are arranged with mutual gap S among them, or bundled into SZ twisting with the mutual gap S, fill the center space with a fixing material 10 by an elastomer, and are mutually bonded separably from each other by the fixing material 10.
