Method and apparatus for manufacturing a ferrule
 A method for manufacturing a ferrule having butt end face on the front and positioning holes on both sides in the width direction and formed with plurality of fiber holes for inserting optical fibers, arranged in such a manner as to be inclined in the thickness direction, by using at least two molds which are arranged in an opposed manner and either or both of which can be moved in the opening/closing direction. Each of at least two molds has a first forming wall for forming the butt end face and a second forming wall for forming a working portion for applying a pressing force perpendicular to the butt end face at the rear of the ferrule. A core for forming the fiber hole and molding pins for forming the positioning holes are arranged in parallel and held in such a manner as to be inclined at a predetermined angle .theta. in the thickness direction of the ferrule molded by at least two molds.
