Beschreibung
Zusammenfassung:	A hot press processing apparatus 1 includes: a heating step of heating a workpiece W; a pressing step of press-molding, by an upper die 11 and a lower die 12, the workpiece W heated in the heating step after loading the workpiece W between the upper die 11 and the lower die 12; and a cooling step of bringing the coolant into contact with a front surface of the workpiece W that is molded and placed in a pressed state by the pressing step, to thereby cool the workpiece W and place the workpiece W in a quenched state. In the hot press processing apparatus 1, the workpiece W molded and placed in the pressed state by the pressing step forms gaps c2 with respect to both of the upper die 11 and the lower die 12 so as to allow deformation at time of the cooling step except for an accuracy-guaranteed section Wr in the workpiece W.
