Optical connector, optical connector module, and method for producing optical connector

An optical connector, comprising:

• a plurality of optical transmission members;
• and a ferrule configured to hold the plurality of optical transmission members,
• wherein the ferrule includes:
• an alignment part for aligning the plurality of optical transmission members in a first direction,
• a first surface disposed to face an end surface of the plurality of optical transmission members aligned by the alignment part, the first surface being for allowing incidence of light emitted from the plurality of optical transmission members or allowing emission of light traveling inside the optical connector to an outside,
• a second surface for allowing emission of the light incident on the first surface to the outside or allowing incidence of light from the outside,
• a recess that is disposed between the alignment part and the first surface and includes a non-contact region corresponding to an end portion of the plurality of optical transmission members aligned by the alignment part, the recess being a recess in which the plurality of optical transmission members are disposed without contacting the non-contact region, and
• a lid for adjusting a position of the end surface of the plurality of the optical transmission members with respect to the first surface by pressing the plurality of optical transmission members by using a pressing surface of the lid, the pressing surface being configured to contact the plurality of the optical transmission members,
• wherein a region of the pressing surface is smaller than a region of the non-contact region in plan view, and
• wherein:
• the recess includes a first contact surface that is a flat surface for supporting the lid;
• the lid includes a second contact surface that is a flat surface for contacting the first contact surface;
• and
• the pressing surface is inclined with respect to the second contact surface.
