To provide a ferule capable of mass-producing various kinds of the ferrules of an SC type, an ST type, an MU type and an LC type, etc., which are secondary molded articles at low cost by turning a highly accurate ferrule body which is a primary molded article injection molded in an insertion pipe to an insertion component and injection molding a base part on a rear end side, and to provide its manufacturing method.
The ferrule 19 is constituted of the ferrule body 1 for which a resin molded part 2 forming a fiber mounting hole 4 at an axial center is integrally provided inside the insertion pipe 3 forming an outer cylinder and a locking part 7 is provided on the rear end outer periphery of the insertion pipe 3, and a cylindrical base part 20 resin molded on the rear end side of the ferrule body 1, for which the fiber mounting hole 21 continued to the fiber mounting hole 4 of the ferrule body 1 is formed at the axial center. The base part 20 is integrally joined with the resin molded part 2 of the ferrule body 1 in the form of covering the locking part 7 of the insertion pipe 3.
