This invention relates to a ferule of an optical connector for connecting optical fibers with each other, and an object of the invention is to provide a ferule of an optical connector that can fix and mold a pipe favorably as well as can be manufactured easily. As a solving means, there is provided a ferule for an optical connector for fixing and holding the ends of the optical fibers and optically coupling the optical fibers with each other by inserting ferules from both the ends of a sleeve, the ferule being arranged such that a metal or non-metal pipe 4 having cut portions 8, which are filled with a resin, or protruding portions 9, which protrude into the pipe and the peripheries of which are filled with the resin, is used, the cut portions 8 or the protruding portions 9 being formed at any one of the rear and front ends of the pipe at one position or a plurality of positions, and the base section 2 of the ferule is covered with the pipe by insert molding the pipe as well as the rear end of the pipe 4 is buried in a collar portion 5 formed to the base section.
