Japanese Patent JP7205520

To alleviate elongation of an area to be elongation-deformed more efficiently when press molding a metal plate into a target press component shape.SOLUTION: According to a press component manufacturing method, when press molding a metal plate into a target press component shape, a position where there is a preset elongation deformation amount or more or a position where it is wanted to increase compressive stress in an area to be elongation-deformed is so made as to be an adjustment part P. The method has, as a press molding process, a first process 3 in which one or more excessive metal parts 20, which are deformed in a plate thickness direction with respect to at least one plate part of both sides with the adjustment part P interposed therebetween, are formed in a deformation direction of elongation deformation, and a second process 4A in which the excessive metal part 20 formed in the first process 3 is collapsed. The excessive metal part 20 formed in the first process 3 has a cross section along the deformation direction of elongation deformation, which becomes an unsymmetrical shape in a direction in which a material movement amount to the adjustment part P relatively becomes more than a material movement amount to a side opposite to the adjustment part P, for example, when being collapsed in the second process 4A.SELECTED DRAWING: Figure 2
