PROBLEM TO BE SOLVED: To prevent deformation or breakage of outermost edge part blades disposed on circumferential outermost edge parts on a contact surface of a mold body of a split mold, and further to prevent deformation or breakage of circumferential edge parts on the contact surface of the mold body due to the deformation or the breakage of the outermost edge part blades. SOLUTION: The tire vulcanization molding mold 1 includes a plurality of split molds disposed so as to surround the circumferential surface of a green tire as an object to be vulcanized. The split mold 2 incldues: the mold body 4 having the contact surface which is caused to contact with the outer circumferential surface of the green tire; and the blades 5 disposed on the contact surface 3 of the mold body 4, and the outermost edge part blades 10 disposed on the circumferential outermost edge parts on the contact surface 3 of the mold body 4 are made to be more flexible than central part blades 20 disposed on the central part in the circumferential direction on the contact surface 3 of the mold body 4.
