PROBLEM TO BE SOLVED: To reduce trouble in injection molding performed by combining an in-mold transfer molding method with an insert molding method.SOLUTION: A cavity 40 for a metal plate 51 and a molding resin part 53 is formed by clamping a first mold 10 and a second mold 20. A transfer sheet 30 for forming a transfer layer 30b on the molding resin part 53 in the injection molding is arranged on a transfer sheet arrangement part P2 of the first mold 10 and the second mold 20 and arranged on the metal plate 51 material in a superposed manner. The first mold 10 and the second mold 20 are provided in the vicinity of the first region 51a of the metal plate 51 on which the transfer sheet 30 and the molding resin part 53 are superposed, and have a cooling groove 15 and a second cooling circuit 20e through which a cooling wind for cooling a first region 51a to be lower than that of a second region Ar3 around the cavity 40 in contact with the molding resin part 53 passes.
