Claim 6:
7. A method for manufacturing a ferrule structure, the method comprising:
forming unit holes on a ferrule that optically connects a respective optical fiber with another optical component, each of the unit holes comprising a step part;
molding lens units from a resin that transmits an optical signal, wherein each of the lens units comprises:
a lens part;
a fiber hole comprising an abutment part; and
a flange part having a diameter greater than a diameter of the unit holes;

attaching the lens units to an end part of the optical fiber by:
inserting an end part of the optical fiber into the fiber hole, wherein a sheath of the optical fiber has been removed at the end part,
aligning the optical fiber with the lens part by abutting an end face of the optical fiber against the abutment part, and
fixing the optical fiber in the fiber hole; and

fixing each of the lens units by:
inserting each of the lens units attached to the optical fiber into one of the unit holes of the ferrule, and
aligning the ferrule and the lens units by contacting the flange part with the step part.
