Abstract
A vulcanization mold including blades having a distal end side and pullout is performed smoothly without causing any failure and a pneumatic tire. A vulcanization mold in which a blade has a proximal end, a blade distal end side expanded in a thicknesswise direction on the distal end side, and a blade connection portion that connects the proximal end portion and the blade distal end side is a vulcanization mold in which a sweep area is the difference where a cross sectional area of the blade connection is subtracted from an area blade distal end side to a mold surface with a width equal to a maximum width of a thickness of the blade distal end side in a cross sectional shape perpendicular to a tire widthwise direction of the blade is smaller in circumferential end side regions than in a circumferential central side region of the sector mold.
