A first extruded shape member has a protrusion projecting from an upper surface of a flat panel portion toward a direction from which a friction stir welding tool is to be inserted. A side surface of the protrusion is connected to the upper surface of the flat panel portion via a small arc R2 and a large arc R3. A second extruded shape member is formed substantially in the same manner. The friction stir welding tool has a small diameter portion formed to the end thereof, and carries out friction stir welding with the center of the small diameter portion positioned to correspond to the joining surface. A joint portion of the welded members has a flat upper surface, and on both sides thereof are formed weld flashes B1. The weld flashes B1 are cut and removed to finish the joint portion.
