Kind Code:

Abstract:
This method for producing a press-molded product is a method for producing a press-molded product (30) comprising a long top plate (2), edge line parts (32a, 32b) on both lateral edges of the top plate, and vertical walls (33a, 33b) that face one another and that extend from the edge line parts. Using a die (21) and punch (22), with the punch in contact with a first part in which the line edge parts are formed on both edges of a blank (BL), the blank is made to curve so as to protrude from the punch side towards the die side, and the second part which forms the top plate in the blank is pinched between the die and the punch, making the second part recessed from the die side towards the punch side.
