The object of the present invention is to provide a vulcanization molding and its vulcanizing machine in which a heating pressure medium, which is nitrogen gas, is heated at high heat exchange ratio without an increase in the running cost and an increase in size. The vulcanizing machine includes a mold mechanism such as a lower side mold 5 and an upper side mold 25 and the like, which removably accommodate a green tire 4, an agitating mechanism 30, which agitates a heating pressure medium such as nitrogen gas or the like, which vulcanization mold the green tire 4 by heating the green tire 4 while pressing it against the mold mechanism, and an induction heating mechanism 41, which preferentially heats the agitating mechanism 30.
