Summary:PROBLEM TO BE SOLVED: To complete a vulcanization molding in a short time. SOLUTION: This vulcanizer is equipped with a bladder 20 which has a magnetic material in at least a part thereof and extends by the supply of a pressurizing medium such as vapor or nitrogen gas and further, pushes a green tire in the mold direction while the tire inner wall face of the green tire and a second inductive heating coil 23 for generating heat in the bladder 20 itself by inductively heating the magnetic material of the bladder 20. Further, the vulcanization molding of the green tire 4 is performed by using the quantity of heat of the bladder 20.
