PROBLEM TO BE SOLVED: To provide a joining method for joining metallic members with each other by using a joint member by which the preliminary friction stir welding can be efficiently performed before performing the permanent joining of the metallic members with the joint member. SOLUTION: When performing a temporary joint joining process for performing the friction stir welding of a butted part J1 of one tab member 1 to a joint member 20, a butted part J2 of a body part 1A of one metallic member 10 to the joint member 20, a butted part J3 of the other tab member 2 to the joint member 20, and a butted part J4 of a body part 1A of the other metallic member 10 to the joint member 20, the starting position S<SB>1</SB>and the terminating position E<SB>1</SB>for the friction stir welding are provided on one tab member 1, and a rotary tool A for temporary joining inserted in the starting position S<SB>1</SB>is relatively moved to the terminating position E<SB>1</SB>without detaching it on the way.
