Abstract
A method of manufacturing a press-formed article includes first press forming and second press forming. In the first press forming, an intermediate formed article is formed from a metal sheet by subjecting the metal sheet to processing including performing draw-forming on the metal sheet to form a peripheral wall portion, bending the metal sheet to form a convex flange portion, and bending the metal sheet to form at least a side standing flange main body portion of a side standing flange portion and a floor flange main body portion of a floor flange portion. The second press forming includes bending the intermediate formed article to form the convex flange portion to an inclined flange portion.
