Abstract
An optical connector includes an optical fiber that includes a glass fiber and a resin coating portion, a ferrule that includes a ferrule main body holding the glass fiber and a flange portion fixed to the ferrule main body, a housing that accommodates the ferrule and includes an inner wall surface facing the ferrule, and an elastic member that is accommodated in the housing and applies an elastic force to the ferrule in a longitudinal direction of the housing. The housing is configured to have a space between the inner wall surface and the flange portion, and the housing is configured such that at least a part of the housing including the inner wall surface is deformed in a state where the housing is engaged with the adaptor, and the inner wall surface prevents rotation of the flange portion with respect to the housing.
