A vulcanization apparatus provided with a vulcanization vessel for vulcanizing a green tire and a suction line for sucking out gas from inside the vulcanization vessel after the vulcanization vessel has been opened. Accordingly, oily smoke generated when vulcanized rubber has been removed from a bladder and an inner wall of a mold can be more efficiently discharged than in cases in which gas inside a vulcanization vessel is sucked out and additional air is introduced into the vulcanization vessel only prior to opening the vulcanization vessel.
