PROBLEM TO BE SOLVED: To provide a tire vulcanizing/molding mold which can dissolve a fault caused by drill breakage by preventing the deformation of a vent hole. SOLUTION: In the tire vulcanizing/molding mold in which an annular mold part 1 contacting the tread part of the tire is formed by combining sectors 5 divided in the tire circumferential direction, the vent hole 8 is formed in each of recesses 6 for molding a land part formed in the inner circumference surface 1a of the annular mold part 1, and the central position of the vent holes 8a and 8b nearest to a sector end E1 is separated by at least 5 mm in the tire circumferential direction from the sector end E1.
