PROBLEM TO BE SOLVED: To provide an injection molding machine in which gas present in a cavity can be discharged outside in a short time by simple configuration wherein only the structure of a partial mold is changed. SOLUTION: The injection molding machine 1 comprises a compressed fluid channel 6 which is formed in relation to the parting plane of at least one of a movable mold 3 and a fixed mold 4 and through which the compressed fluid E flows, a suction force generation part 8 which is formed by contracting the aperture of part of the compressed fluid channel, and a contact channel 10 in which one end is connected to the suction force generation part, and the other end is connected to a degassing spout 9 formed on the periphery of the cavities 19 and 20 of the mold.
