Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heater for a tire valcanizing mold which efficiently prevents heat loss from an electromagnetic induction heating element which generates heat by electromagnetic induction heating, and significantly increases heat transmission efficiency to a tire contact surface of the vulcanizing mold.SOLUTION: The heater for a tire valcanizing mold, which partitions a vulcanizing molding cavity 5 of a raw tire in cooperation with a vulcanization bladder 4, includes vulcanization mold parts 1, 2, 3. At least a contact surface with the tire is partitioned by a member formed of a metal material with small magnetic permeability and exhibiting excellent heat conductivity. The electromagnetic induction heating elements 11, 12, 13 formed of a metal material with large magnetic permeability are arranged in predetermined positions separated from the contact surface with the tire. Coils 14, 15, 16 for generating heat from the electromagnetic induction heating elements 11, 12, 13 are arranged in platen side members 7, 9, 10 on which the vulcanization mold parts 1, 2, 3 are mounted.
