PROBLEM TO BE SOLVED: To provide a welding structure having a fillet welding joint excellent in a brittle crack propagation stop characteristic.SOLUTION: The welding leg length and a welding width of a fillet welding joint exceed 16 mm, and a butting surface of an end surface of a joining member and a surface of a joining object member in the fillet welding joint is provided with an unwelded part of 95% or more of a plate thickness tw of the joining member in a cross section of the fillet welding joint. On fillet welding metal of the fillet welding joint, the predetermined relationship is satisfied between the Charpy impact test broken surface transition temperature vTrs(°C) of the fillet welding metal, and a plate thickness tf of the joining object member, or further L being smaller value of the welding leg length and the welding width.SELECTED DRAWING: Figure 6
