Claims

[Scope of utility model registration request]

In a terminal portion that accommodates a plurality of optical fibers, the terminal portion includes a first pipe having a multicore hole into which an optical fiber wire is inserted, and a second pipe into which a portion of the first pipe is fitted, Each of the multicore holes is formed with a taper that widens toward an end surface of the first pipe accommodated in the second pipe, and each taper further has an apex on the central axis of the first pipe. An optical fiber terminal section, characterized in that the optical fiber terminal section is connected to a taper that widens toward the end surface.
