PROBLEM TO BE SOLVED: To provide a joining method capable of easily flattening a joined metallic member.SOLUTION: A joining method includes executing the frictional agitation in a state of inclining metallic members 1 and 1 so that one end side becomes higher than the other end side of the metallic members 1 and 1 in a first regular joining step, removing a burr generated by the frictional agitation and reversing the metallic members 1 and 1 after finishing the first regular joining step, and after a second regular joining step, executing a correction step of correcting warping of projecting to the surface side of the metallic members 1 and 1 formed by frictional agitation in the second regular joining step. |
