PROBLEM TO BE SOLVED: To suppress welding residual stress and deformation of a welded portion generated on a welded structure of members, to effectively improve welding operation. SOLUTION: The welded structure comprises a base 15, a bar member 31 fixing the base 15 on a fixing portion 41 and having a projecting portion 42 ranging to the fixing portion projected from the base, and the welded portion 32 fixing the fixing portion to the base. The welded portion 32 comprises a standard bead 53 applied by staggered welding and applied to a position most close to the tip 45 of the projecting portion, and a remaining bead 54 applied to a position offsetting moment force which is generated on the projecting portion on the basis of the standard bead.
