PROBLEM TO BE SOLVED: To uniformly heat a heated material formed in cylindrical shape without temperature unevenness. SOLUTION: A vulcanization molding device 10 comprises an inner die 20 and an outer die 40. The outer die 40 has circumferentially divided outer die pieces 41, 42, 43. The inner die 20 is disposed radially inside the outer die pieces 41, 42, 43. The heated material 30 presenting cylindrical shape is mounted on the outer peripheral surface of the inner die 20. Cylinders 51, 52, 53 are provided outside the outer die pieces 41, 42, 43. The cylinders 51, 52, 53 radially displace the outer die pieces 41, 42, 43. When the outer die pieces 41, 42, 43 are displaced radially inward, their inner peripheral surfaces 41B, 42B, 43B come in close contact with the outer peripheral surface 32 of the heated material 30. In this close contact state, high frequency voltage is applied between the inner peripheral surfaces 41B, 42B, 43B and the outer peripheral surface 32. COPYRIGHT: (C)2007,JPO&INPIT
