PROBLEM TO BE SOLVED: To provide a method and an apparatus for measuring an ambient atmosphere in a cavity formed in a metallic die of an injection molding machine, by which method and apparatus, a furthermore exact measurement value can be achieved by directly measuring the ambient atmosphere in the cavity. SOLUTION: The apparatus 30 for measuring the ambient atmosphere inside the die is configured to have a rod 31 which is inserted into the metallic die 10, and at least partially faces to the inside of the cavity 13, a cylinder 32 for driving the rod 31 to the advanced position in the cavity 13 and to the receded position from the cavity 13, a measuring gas passage 31a formed inside the rod 31, and a measuring instrument 34 having a detecting element 33 arranged inside the measuring gas passage 31a. An opening port 31b of the measuring gas passage 31a is provided at a part of the advanced portion of the rod 31 into the cavity 13. In the state that the rod 31 is receded, the measuring gas passage 31a is closed, and the cavity side end face 31d of the rod 31 forms a part of the formed surface of the metallic die 10.
