Disclosed is a hot-pressing die capable of quenching a workpiece at a sufficient cooling rate without increasing a pressure at which the workpiece is pressed, and a method for manufacturing the hot-pressing die. The die (10) which presses and cools a heated workpiece (W) at the same time to form a product (P) with a hat-shape includes a lower die (101) and an upper die (102). The lower die (101) has a protrusion (101a) which protrudes from the forming surface thereof, and the upper die (102) has a recess (102a) corresponding to the protrusion (101a). The lower die (101) is modified into a modified lower die (11) by forming, on the forming surface of the protruding end of the protrusion (101a), a buildup part (13) with a convex shape to gradually change in position in the protruding direction of the protrusion (101 a) toward the middle thereof. |
