Claims (1)

[Claim for Utility Model Registration] In the terminal structure of a plastic optical fiber inserted into a ferrule, a recess in which the plastic optical fiber terminal part is to be positioned is formed on the distal end surface, and a part of the periphery of the recess in the circumferential direction is the remaining part. A plastic optical fiber is inserted into a ferrule that has been cut to shorten its axial dimension, and the proximal end of the ferrule is pressed from the outside to partially reduce its inner diameter and the plastic optical fiber becomes a ferrule. A terminal of a plastic optical fiber, wherein the end face of the terminal part of the plastic optical fiber is comprised of a cut surface cut with a knife and a very slight broken surface formed by bending. structure.
