PROBLEM TO BE SOLVED: To provide a method of injection molding and an injection molding machine evacuating the inside of a cavity for easily fluidizing a molten material, and suppressing occurrence of gas from the molten material injected into the cavity. SOLUTION: In the method of injection molding injecting the molten material Mm from an injection device 11 into the cavity 53 formed between a fixed die 13 and a movable die 14 and evacuated, the molten material Mm plasticized in a heating cylinder 15 evacuated by an evacuation means 36 is injected into the evacuated cavity 53, to easily fluidize the molten material Mm in the cavity 53, and to suppress generation of gas from the molten material Mm.
