PROBLEM TO BE SOLVED: To provide a method of calculating the inserting position of a rotary tool in the case a filler is inserted into a gap. SOLUTION: In the friction stirring-joining method, two members 11 and 12 are butted, the butted parts are cut with a cutter 20 to provide a slit 14, a filler 21 is inserted into the slit 14 with rollers 22, 23 and 25, and the filler 21 and the two members 11 and 12 on both the sides thereof are subjected to friction stirring-joining with a rotary tool 35. In the rotating direction of the rotary tool 35, the position of the gap between the end part of the filler 21 on the upstream side and either member 11b on the upstream side in the rotating direction is obtained with an optical sensor 35, the half of the width of the filler 21 is added to the position, and the added position is decided as the position of the rotary tool 35.
