To provide a friction welded joint in which one or both of base material steel plates are Al plated and exhibit high joint strength, a tailored blank material, a molded article, and a method for manufacturing the friction welded joint.SOLUTION: A friction welded joint according to one aspect of the present invention comprises: a first steel plate plated with Al; a second steel plate disposed on substantially the same plane as that of the first steel plate; and a friction welded surface that joins the end surfaces of the first and second steel plates. Al plating is discharged from a joint part. A friction welded joint according to another aspect of the present invention comprises a first steel plate plated with Al, a second steel plate disposed on substantially the same plane as that of the first steel plate, and a friction welded surface that joins the end surfaces of the first and second steel plates. An average Al amount in the joint part is less than 1.0 mass%.SELECTED DRAWING: Figure 1 【課題】母材鋼板の一方又は両方がＡｌ系めっきを有しながら高い接合強度を有する摩擦圧接継手、テーラードブランク材、成形品、及び摩擦圧接継手の製造方法を提供する。【解決手段】本発明の一態様に係る摩擦圧接継手は、Ａｌ系めっきを有する第１の鋼板と、前記第１の鋼板と実質的に同一平面上に配された第２の鋼板と、前記第１の鋼板の端面と、前記第２の鋼板の端面とを接合する摩擦圧接面と、を備え、接合部から、前記Ａｌ系めっきが排出されている。本発明の別の態様に係る摩擦圧接継手は、Ａｌ系めっきを有する第１の鋼板と、前記第１の鋼板と実質的に同一平面上に配された第２の鋼板と、前記第１の鋼板の端面と、前記第２の鋼板の端面とを接合する摩擦圧接面と、を備え、接合部における平均Ａｌ量が１．０質量％未満である。【選択図】図１
