PROBLEM TO BE SOLVED: To provide an injection mold capable of realizing highly efficient low cost production when one or more kinds of injection-molded products are formed, and a manufacturing method for an injection-molded product. SOLUTION: The injection mold 1 is equipped with a pair of molds 2 and 3, which form cavities 4 and 5 between them and are provided so as to be separated and allowed to approach mutually, and a supply part 80 for supplying a molten resin into the cavities 4 and 5. The cavities 4 and 5 are independently provided within the mold on-off surfaces of a pair of the molds 2 and 3, and the supply part 80 has runners 39 and 63 separately communicating with the respective cavities 4 and 5 and a sprue bush 30 having the sprue 36, which communicates with the runners 39 and 63, formed thereto. The sprue bush 30 is equipped with an opening/closing mechanism 37 capable of selectively supplying the molten resin to the cavities 4 and 5. COPYRIGHT: (C)2004,JPO
