A method of manufacturing an optical connector according to the invention includes: holding a first optical fiber by a pair of holding members at a position apart from an end face of a second end and through both sides thereof in a radial direction, the first optical fiber being provided with a solid refractive index-matching material layer, the refractive index-matching material layer being formed on the end face of the second end on an opposite side of an end face of a first end exposed to a front end of a ferrule; and inserting the first optical fiber into a fiber hole of the ferrule through the first end.

Method of manufacturing optical connector, optical connector, and optical fiber insertion device

A holder includes a base including a reference surface and a slider to which an optical-fiber retainer that retains an optical-fiber can be attached. The slider is movable in a front-rear direction with respect to the base, and at least a portion of the optical-fiber retainer is accommodated between the reference surface and the slider when the optical-fiber retainer is attached to the slider and the optical-fiber retainer is positioned with respect to the reference surface by moving the slider toward a reference surface side.
