1. A method for manufacturing an optical fiber connection component, comprising:
preparing one or a plurality of optical fibers each of which includes a glass fiber and a resin coating portion covering the glass fiber and in each of which an end portion of the glass fiber is exposed from the resin coating portion, the glass fiber including a core and a cladding that covers the core, and the glass fiber having a structure that is not axially symmetric with respect to a central axis of the glass fiber in a cross section perpendicular to the central axis;
mounting the one or the plurality of optical fibers on a first optical fiber holding member so that one or a plurality of glass fibers exposed from the resin coating portion are arranged side by side in a first direction and protrude to an outside from the first optical fiber holding member;
adjusting an azimuth around a central axis for the one or the plurality of optical fibers;
bonding the one or the plurality of glass fibers to the first optical fiber holding member using a first bonding agent;
mounting the one or the plurality of glass fibers on a second optical fiber holding member so that one or a plurality of glass fibers protruding to the outside from the first optical fiber holding member are arranged side by side in the first direction;
bonding the one or the plurality of glass fibers to the second optical fiber holding member using a second bonding agent; and
grinding an end face of the one or the plurality of glass fibers and an end face of the second optical fiber holding member so that the end face of the one or the plurality of glass fibers is flush with the end face of the second optical fiber holding member.
