Method for manufacturing pressed component, metal sheet for press forming, and high-tensile steel sheet

A method for manufacturing a pressed component including forming a metal sheet into a pressed component shape having:

• a cross section having a top sheet portion, a side wall portion continuous to at least one side in a width direction of the top sheet portion via a first bent portion, and a flange portion continuous to the side wall portion via a second bent portion;
• and having one or more curved portions in which the top sheet portion is curved to project or to be recessed in a side view along a longitudinal direction in a direction-intersecting the cross section,
• the method comprising:
• a second preliminary forming step having a step of forming, to the metal sheet, a second bead continuously or partially extending along the longitudinal direction at a position where the second bent portion is formed, wherein the second bead has a shape of being recessed in a same direction as a recessing direction of the second bent portion;
• and
• a second component forming step of forming the metal sheet after the second preliminary forming step into the pressed component shape.

A metal sheet for press forming, the metal sheet being press formed into a pressed component shape having:

• a cross section having a top sheet portion and a side wall portion continuous to at least one side in a width direction of the top sheet portion via a first bent portion;
• and having one or more curved portions in which the top sheet portion is curved to project or to be recessed in a side view along a longitudinal direction intersecting the cross section,
• the metal sheet comprising:
• a first bead continuously or partially extending along the longitudinal direction at a position where the first bent portion is formed, wherein the first bead has a shape of projecting in a same direction as a projection direction of the first bent portion.
