Provided is a friction stir welding method that can advantageously obtain a joined article having a sound joined section without defects in two materials of the same or different materials among an aluminum alloy mold or a 2000-series, 4000-series, 5000-series, and 7000-series aluminum alloy material, which are considered to be difficult to join during friction stir welding. An ending tab material (20) comprising a 1000-series aluminum alloy, a 3000-series aluminum alloy, a 6000-series aluminum alloy, or an 8000-series aluminum alloy is abutted to the end surface of the joining ending end of the joining site (abutted section (6)) of a first member (2) and second member (4), and after the probe (16) of a rotating tool (10) is led from the joining site of the two members (2, 4) into the ending tab material (20), the friction stir welding operation of the first member (2) and second member (4) is ended. |
