Claim Text:
1. An optical fiber assembly comprising: a plurality of optical fibers; an alignment member that is arranged at distal ends of the plurality of optical fibers and that aligns and holds the distal ends of the plurality of optical fibers; a first adhesion part where the alignment member and the plurality of optical fibers are bonded by a first adhesive agent having curability; a second adhesion part where the plurality of optical fibers are bonded to each other at a position within a predetermined distance from a rear end of the alignment member that is arranged at the distal ends of the plurality of optical fibers and bonded to the plurality of optical fibers in the first adhesion part, by a second adhesive agent that has, after being cured, greater flexibility than the first adhesive agent; and fiber trunk side-adhesion parts provided at a plurality of locations in a longitudinal direction of the plurality of optical fibers, the fiber trunk side-adhesion parts each being composed of the plurality of optical fibers bonded to each other by a third adhesive agent that has, after being cured, greater flexibility than the first adhesive agent, wherein the plurality of optical fibers include three or more optical fibers, and wherein at least one of the optical fibers is left non-bonded in the fiber trunk side-adhesion part.
