To provide a method for manufacturing a joined body capable of making the finish of the surface of the joined body excellent, as well as, capable of preventing a rotating tool from being damaged.SOLUTION: A method for manufacturing a joined body in which a jacket body (first metal member 2) and a seal body (second metal member 3) are friction stir welded together. In the method: at a main joining step, there is a separation zone in which an end position EP1 is set on the jacket body 2 on an outer side of a set movement route L1, and a first abutted section J1 is friction stir welded, after which a rotating tool F is moved to the end position EP1 and the rotating tool F is separated from the jacket body 2 at the end position EP1; at the main joining step, a stir pin F2 is rotated at a prescribed rotation speed to friction stir weld the first abutted section J1; and in the separation zone, the rotating tool F is moved toward the end position EP1 while gradually lowering the rotation speed thereof from the prescribed rotation speed and the rotating tool F is separated from the jacket body 2.SELECTED DRAWING: Figure 5 【課題】接合体の表面の仕上がりを良好にすることができるとともに、回転ツールの破損を防ぐことができる接合体の製造方法を提供することを課題とする。【解決手段】ジャケット本体（第一金属部材）２と封止体（第二金属部材）３とを摩擦攪拌で接合する接合体の製造方法であって、本接合工程において、設定移動ルートＬ１よりも外側のジャケット本体２に終了位置ＥＰ１を設定し、第一突合せ部Ｊ１に対する摩擦攪拌接合の後、回転ツールＦを終了位置ＥＰ１に移動させつつ、終了位置ＥＰ１でジャケット本体２から回転ツールＦを離脱させる離脱区間を有し、本接合工程は、所定の回転速度で攪拌ピンＦ２を回転させて第一突合せ部Ｊ１の摩擦攪拌接合を行い、離脱区間において、所定の回転速度よりも徐々に回転速度を下げながら回転ツールＦを終了位置ＥＰ１に向けて移動させて、回転ツールＦをジャケット本体２から離脱させる。【選択図】図５
