Abstract: A hot forming die according to an exemplary embodiment can be provided for a press forming apparatus which can press-forms a heated metal plate (e.g., a work material) and may cool the work material by ejecting a cooling medium onto the work material. The hot forming die can have a main supply path through which the cooling medium passes, a plurality of branch supply paths branching off the main supply path, injection ports for ejecting the cooling medium to the outside of the die, and nozzle members fixed on the ejection port side of the branch supply paths to restrict the passage amount of the cooling medium by using passage holes for allowing the cooling medium to pass there through. In a hot press forming method according to an exemplary embodiment, the cooling medium in the die can be held on standby after being pressurized to a degree at which the cooling medium is not ejected.
