A curing mold of the tire vulcanizer bladder comprises a lower bladder curing mold(2b) equipped with a heat supply chamber(1b) which is manufactured so that the external side of a bladder(102) is formed, a core mold(3) equipped with a heat supply chamber(1c) which contacts directly to the inner surface of bladder and delivers the heat, an end core(4) contacting with the upper part of the core mold and top bladder curing mold(2a) and supplying the rubber for bladder in an injection method. The upper and lower parts of bladder have larger diameters than the middle part.
