Abstract
A vulcanization mold in which a blade 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 portions to each other, is a vulcanization mold wherein a sweep area that is the difference where a cross sectional area of the blade connection portion is subtracted from an area from the blade distal end side thick portion to a mold surface with a width equal to a maximum width of a thickness of the blade distal end side thick portion in a cross sectional shape perpendicular to a tire widthwise direction of the blade is smaller 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.
