A lap-fillet arc-welded joint having a first metal plate, a second metal plate, and a weld bead, said lap-fillet arc-welded joint characterized in that: a region at one end of the first metal plate is bent; in a first direction in a cross-sectional view of a cross section perpendicular to the weld line of the weld bead, the position of the tip-end of the bent region of the first metal plate overlaps a region at one end of the second metal plate, and in a second direction, the amount of offset between the center axis of a region continuous with the bent region of the first metal plate and the center axis of the region at the one end of the second metal plate is no greater than one-half the average value of the plate thicknesses of the first metal plate and the second metal plate; the weld section length, which is the length from the root part of the second metal plate to the weld toe portion of the first metal plate, is at least twice the plate thickness of the second metal plate; and the position of the weld toe portion of the first metal plate in the second direction is in a range from a first position to a second position.
