Abstract

A metal sheet for press forming has a shape such that a boundary position between the region corresponding to the curved portion and an other region in the region corresponding to a curved portion is rotationally displaced in-plane around a rotational center set at a position on a curved recessed side rather than a position corresponding to a ridge line between a top sheet portion and a vertical wall portion on the curved recessed side, in a direction in which a line length of an outer edge of a position to be formed into the flange portion on a curved protruding side in the region corresponding to a curved portion approaches a line length of an outer edge of the flange portion on the curved protruding side in the press-formed component shape.
