Abstract:
Provided is a press-molded product capable of improving the bonding strength between a vehicle body reinforcing member and the other member or the rigidity of a vehicle body by enlarging a cross-section of a member to a fullest extent of a design cross-section without forming a notch for preventing a press-molding failure in a ridge-portion flange.A press-molded product is formed by a steel plate having a tensile strength of 340 MPa or more, and includes an inward continuous flange in at least one end portion in a predetermined direction, the inward continuous flange being obtained by continuously forming a ridge-portion flange formed inward in the end portion of the ridge portion, a first flange formed inward in at least a part of an area of the end portion of a first surface portion, and a second flange formed inward in at least a part of an area of the end portion of a second surface portion.
