PROBLEM TO BE SOLVED: To solve the problem wherein, as a result of allowing a gate and a molded product to be spaced apart from each other when separating the gate from the molded product and cutting and separating the gate and the molded product so as to tear off them, a protrusion remains on the molded product after the gate is torn off not only to markedly lower the value of the molded product but also to apply a feeling of physical disorder to a finger by the gate mark of the protrusion to often bring about danger causing an unexpected injury by the gate mark. SOLUTION: This injection mold constituted so that a cavity, where the molded product is molded, is provided in a pair of split molds, the runner and the gate, both of which communicate with the cavity, are provided in the split molds and a gate bush for holding the runner and a sleeve pin for ejecting the molded product are arranged.
