Claim Text:
1. A forming method that forms a press component with an L shape from a blank metal sheet, the press component having a top sheet section and a vertical wall section, that comprises a bent section, which is connected to the top sheet section via said bent section having a portion curved in an arc shape and which has a flange section on an opposite side to the bent section, the top sheet section being arranged at an outside of the arc of the vertical wall section, and the flange section having an edge, the method comprising: disposing a first portion of the blank metal sheet between a pad and a portion of a die corresponding to the top sheet section, and disposing a second portion of the blank metal sheet which is different in position from the first portion of the blank metal sheet between a bending die and a portion of the die corresponding to the flange section; and forming the vertical wall section and the flange section while an edge of the blank metal sheet corresponding to a bottommost edge of the L shape is caused to slide on the portion of the die corresponding to the top sheet section by vertically moving the bending die closer to the die, the forming of the vertical wall section and the flange section being performed in a state where: the pad puts pressure on at least a portion of the blank metal sheet which is put on the portion of the die corresponding to the top sheet section so as to provide an out-of-plane deformation suppressing area between the pad and the die; the edge of the blank metal sheet corresponding to the bottommost edge of the L shape is arranged on a same plane as the portion of the blank metal sheet which is put on the portion of the die corresponding to the top sheet section; and a portion of the blank metal sheet corresponding to the flange section includes a portion of an edge of the blank metal sheet.
