It is an object to provide a vulcanization mold that 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 1 in which a blade 6 or 7 has a blade proximal end portion 6a or 7a, a blade distal end side thick portion 6c or 7c expanded in a thicknesswise direction on the distal end side, and a blade connection portion 6b or 7b that connects the blade proximal end portion and the blade distal end side thick portion 6c or 7c to each other is a vulcanization mold in which a sweep area Sc or Se that is the difference where a cross sectional area of the blade connection portion 6b or 7b is subtracted from an area from the blade distal end side thick portion 6c or 7c to a mold surface with a width equal to a maximum width of a thickness of the blade distal end side thick portion 6c or 7c in a cross sectional shape perpendicular to a tire widthwise direction of the blade 6 or 7 is smaller at the blades 7 in circumferential end portion side regions E than at the blades 6 in a circumferential central portion side region C of the sector mold 3. Further, a pneumatic tire 20 is manufactured using the vulcanization mold 1.
