Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a stack-mold injection compression molding method which does not generate variation in quality of each product, without increasing production cost.SOLUTION: A stack-mold-type molding mold for injection compressing molding comprises a fixed mold 10, a movable mold 11, a middle mold 12, a first cavity 20 between the fixed mold 10 and the middle mold 12, and a second cavity 21 between the middle mold 12 and the movable mold 11. The fixed mold 10 includes a first runner 15 connecting with a nozzle 14. The middle mold 12 includes a second runner 16 connecting with the first runner 15 when the middle mold 12 and the fixed mold 10 are completely closed. Furthermore, after injection compression molding is implemented in the second cavity 21, injection compression molding in the first cavity 20 is implemented while the movable mold 11 and the middle mold 12 are fixed by mating a convex member 30 and a concave member 31.
