Claims

[Scope of utility model registration request]

It is composed of a lower substrate 5' into which the optical fiber tape is sandwiched, and an upper lid 5 which is rotatably held with respect to the lower substrate, and the lower substrate and the upper lid each have a wave-shaped concave and convex shape, and are assembled with each other. In the optical fiber tape fixing jig of this structure, the lower substrate has a two-stage structure consisting of a wave-shaped groove 6' in which the optical fiber tape is accommodated, and a groove 6'' in which the wave-shaped part of the upper cover, which is wider than the width of the optical fiber tape, is accommodated. An optical fiber tape fixing jig comprising a groove, a protrusion 9 in the concave portion of the corrugated portion, and a horizontal flat portion continuous to the corrugated portion.
