A bushing of an injection mold is provided to refrain from generation of sprue in molding products and exclude post treatment process. A bushing of the injection molding forms a hollow(121) through which resin liquid passes through on its both ends. The hollow consists of an injection pipe tapered from an inlet port(121a) to an outlet port(121b); and a flange, formed with a cavity(111) with which a nozzle of an injector is contacting is formed on its top of the injection pipe, where the cavity is communicated with the hollow.
