PROBLEM TO BE SOLVED: To provide an easily manufacturable steel member capable of surely fixing the other member to a curved surface.SOLUTION: A steel member 100 comprises a steel member body 10 having a curved surface 14 and a welding stud bolt 13 provided on the curved surface 14 of the steel member body 10. The curved surface 14 of the steel member body 10 forms a band shape of curving by drawing an arc, and the welding stud bolt 13 is provided in a plurality along the curving direction V of extending by curving the curved surface 14. Thus, there is no need to form a bolt joining hole for joining to the other member in the steel member body 10. Thus, the other member can be surely fixed to the curved surface 14 of the steel member 100 via the welding stud bolt 13, and the steel member 100 is easily manufactured.SELECTED DRAWING: Figure 1 【課題】曲面に対して他部材を確実に固定させることができ、製造がしやすい鋼製部材を提供する。【解決手段】鋼製部材１００は、曲面１４を有する鋼製部材本体１０と、鋼製部材本体１０の曲面１４に設けられる溶接スタッドボルト１３とを備える。鋼製部材本体１０の曲面１４は弧を描いて湾曲する帯形状をなし、溶接スタッドボルト１３は曲面１４が湾曲して延びる湾曲方向Ｖに沿って複数設けられる。これにより、鋼製部材本体１０には、他の部材と接合させるためのボルト接合用の孔を形成する必要がない。従って、溶接スタッドボルト１３を介して鋼製部材１００の曲面１４に他部材を確実に固定させることができるとともに、鋼製部材１００の製造がしやすくなる。【選択図】図１
