There is disclosed a ferrule including a sheath holding portion (11) and a core wire holding portion (12) which have inner diameters slightly greater than the outer diameters of a sheath portion (a) and a core wire portion (b) of a plastic fiber (A), respectively. The sheath holding portion (11) is provided with a flange portion (11a) which contacts a coiled spring when mounted in a connector housing, and the core wire holding portion (12) includes a large-diameter portion (13) at a front end thereof for receiving a front end portion of the core wire portion (b) of the plastic fiber (A) softened by hot plate treatment. The large-diameter potion (13) has a tapered inner surface such that an inner diameter thereof increases toward the front end, and the angle of flare thereof is 30 degrees. <IMAGE>
