PROBLEM TO BE SOLVED: To perform a good precise friction-stirring joining at a low cost when a standing member is friction-stirring joined to a horizontal member to obtain a joint. SOLUTION: When the end part of the standing member is engaged with a groove part by forming one pair of projecting parts 22 and 23 extended in the longitudinal direction at the longitudinal interval on the main surface of the horizontal member 11 and regulating the groove part 21 with one pair of projecting parts, with the bottom surface in parallel to the main surface and one pair of side surfaces regulated to both ends of the bottom surface extended in the longitudinal direction and forming the end part of the standing member 12 to a projecting-shape for engaging with the shape of the groove part, the joining part is formed so as to have the inclined surface with the projecting parts and the end part of the standing member, and the joining part is subjected to the friction-stirring joining by a friction-joining tool. In this case, the depth of the groove part is regulated not longer than the length of a probe because of the projecting part, and the width of the inclined surface regulating the joining part is regulated not shorter than the diameter of the shoulder part.
