The present invention pertains to a welding structure provided with a fillet welded joint obtained by bringing the weld end surface of a joining member into contact with the weld surface of a butt weld joint of a joined member, both members having a plate thickness of at least 50 mm, and joining the joining member and the joined member by fillet welding. The weld leg length and/or the welding width of the fillet welded joint are 16 mm or less. The welding metal in the butt weld joint of the joining member and/or the joined member is set at -65 DEG at vTrs-W (DEG C), and/or a toughness of at least 140 J is set at vE-20-W (J). A non-welded section exists on the surface where the joining member and joined member are brought into contact, where the cross section of the butt weld joint of the fillet welded joint is no less than 95% of the plate thickness (tw) of the joining member. By satisfying a predetermined relationship between vTrs (DEG C) and/or vE-20 (J) of the fillet welded metal, and the plate thickness (tf) of the joined member, the propagation of brittle cracks is prevented before said cracks lead to large-scale destruction.
