Abstract: The present invention relates to the provision of a ferrule that can be connected even when the space for the connection is small. A ferrule of the present invention is configured to hold a plurality of optical transmission members and to be connected to another ferrule. The ferrule includes a first surface facing the end of the optical transmission members when the optical transmission members are held; and a plurality of second surfaces disposed opposite to the first surface in the ferrule. In the ferrule, the optical transmission members extend in the Z direction, and the ferrule is configured to be moved in a direction orthogonal to the Z direction to be connected to the other ferrule.

Abstract: An optical connector production device of the present invention is configured to produce an optical connector that includes a ferrule and a first optical transmission member. The production device includes a jig body, and a fixing part which allows the ferrule to fit thereto to hold the ferrule and which is disposed in the jig body.

Abstract: A ferrule includes an optical transmission member holding part configured to hold an optical transmission member; a first surface that faces an end portion of the optical transmission member when the optical transmission member is held at the optical transmission member holding part; and a through hole that is open between the optical transmission member holding part and the first surface.

Abstract: This optical receptacle has an optical receptacle main body, a supporting member, and an adhesive. The optical receptacle main body includes a first optical surface, second optical surface, reflecting surface, first fit-in section, and recessed section. The supporting member includes: a supporting member main body; a second fit-in section fitted in the first fit-in section; and a through hole, which faces the recessed section, and which is opened in the inner-side surface of the supporting member main body, and in the outer-side surface on the reverse side of the inner-side surface. The adhesive is in contact with the inner surface of the recessed section, and the supporting member. The optical receptacle main body is disposed further toward the supporting member side than an installation surface.
