Abstract: The head end surface of an optical fiber (2) and the head end surface of an optical fiber (12) are butted to each other in an alignment member (22) of an adapter (21). In the butting, because one of the members clasping the optical fiber (2) is a plate (4a) that is short, the optical fiber (2) is bent and buckled between the left end of the short plate and the right end of the alignment member.
