PROBLEM TO BE SOLVED: To execute frictional agitation joining of a high quality.SOLUTION: A joining method includes a first frictional agitation joining process of executing frictional agitation in a first joining range Rup to a first point provided up to the middle of a butting part J from one end side of the butting part J, a filling process of filling a metallic member Z in an extraction hole Hgenerated when extracting an agitation pin A2 of a rotary tool A from a plasticizing area of a metallic element in the first frictional agitation joining process and a second frictional agitation joining process of executing the frictional agitation in a second joining range Rup to the other end side of the butting part J from a second point provided in the plasticizing area of belonging to the first joining range Rgenerated by the first frictional agitation joining process, and in the first frictional agitation joining process, a start position of the frictional agitation is set on a tab part 3 arranged on side of one end side of the butting part J, and an end position of the second joining range Ris set on a tab part 2 arranged on the side of the other end side of the butting part J on the opposite side of the one end side. |
