PROBLEM TO BE SOLVED: To provide a reactive injection molding machine capable of simply molding a microcellular foamed molded object having a small cell size by using an inert fluid such as carbon dioxide or nitrogen. SOLUTION: A raw material is supplied by raw material quantitative supply pumps 8 and 9, and the inert fluid is supplied by inert fluid quantitative supply pumps 12 and 13 and, thereafter, the premix of the raw material and the inert fluid premixed by premixing units 14 and 15 is pressurized and/or heated by high pressure heaters 16 and 17 to continuously dissolve the inert fluid in the raw material and the premix is ejected under high pressure by a mixing head 14 to be injected in the cavity part 24 of a mold 5 while reacted and, at this time, the generated gas is received by a gas pocket part 25 through a partition part 26.
