To manufacture a frame component having a plurality of closed cross sections with a high productivity.SOLUTION: This invention provides a method for manufacturing a frame component 11 having a substantially rectangular outline 11a which forms a plurality of closed cross sections 12-14 by roll-form molding a metal-made plate 3 with one end 15 remaining outward and the other end 16 disposed inward. This method has a step for forming an abutted part 31 of a T-shaped cross section by abutting the other end 16 of the plate 3 on a first vertical wall 21 (one side wall). It also has a step for welding from outside to weld the other end 16 on the first vertical wall 21.SELECTED DRAWING: Figure 2 【課題】板複数の閉断面を有するフレーム部品を生産性よく製造する。【解決手段】金属製の板材３を一方の端部１５を外方に残し他方の端部１６を内方に配置するようにロールフォーム成形して複数の閉断面１２～１４を内方に形成する略矩形の外郭１１ａを有するフレーム部品１１の製造方法である。第１の縦壁２１（一の側壁）に板材３の他方の端部１６を突き当てて断面Ｔ字状の突当部３１を形成するステップを有する。外方から溶接を施して他方の端部１６を第１の縦壁２１に溶接するステップを有する。【選択図】 図２
