A tire vulcanizer (1) in which occurrence of a temperature difference between the upper and lower portion of a raw tire in a vulcanizing process by the tire vulcanizer is prevented or minimized to stabilize the quality of the tire. The tire vulcanizer (1) has a tire vulcanizing bladder (20) placed inside the raw tire (4), an ejection section (90) for ejecting a heating and pressurizing medium to the inside of the bladder (20), a medium supply path for supplying the heating and pressurizing medium to the ejection section (90), a holding section (14) for holding that portion of the edge of the bladder (20) that is close to the medium supply path, and heat insulation members (7, 11, 8, 6) for suppressing heat transmission from the heating and pressurizing medium, which is ejected from the ejection section (90), to the lower edge of the raw tire (4).
