Abstract
A vulcanization mold is a mold including blades having a distal end side thick portion and pullout is performed smoothly by the mold without causing any failure, and a pneumatic tire. A vulcanization mold in which a blade or has a blade proximal end portion, a blade distal end side thick portion expanded in a thicknesswise direction on the distal end side, and a blade connection portion that connects the blade proximal end portion and the blade distal end side thick portion to each other is a vulcanization mold in which a blade density that is a number of blades implanted on a sector mold per unit length in a circumferential direction is lower at the blades in circumferential end portion side regions than at the blades in a circumferential central portion side region of the sector mold. Further, a pneumatic tire is manufactured using the vulcanization mold.
