A hot-forming apparatus for press- forming a heated metal plate material (1), wherein supply piping (6) for cooling medium is provided in side a metal die (2, 3), and an ejection hole (4) penetrating from a forming surface of the die (2, 3) to the supply piping (6) is provided. Alternatively, discharge piping (7) for the cooling medium is provided inside the die (2, 3), and a discharge hole (5) penetrating from the forming surface of the die (2, 3) to the discharge piping (7) is provided, and further, cooling piping (8) can be provided. The cooling medium is ejected from the ejection hole (4) to a gap between the metal plate material (1) and the die (2, 3) and forming is performed.
