An overlapping portion (30) of a first member (31) and a second member (32) is joined using a tool (1) and a rivet (5) for friction stir spot welding. The overlapping portion (30) is formed by disposing the first member (31) on the side into which the tool (1) is press fitted first, and disposing the second member (32) on the side into which the tool (1) is press fitted last. A friction stirred portion (4) is formed in the overlapping portion (30) by press fitting the tool (1) into the overlapping portion (30) and performing friction stirring. The rivet (5) is press fitted into the friction stirred portion (4) from the first member (31) side. Une partie de chevauchement (30) d'un premier élément (31) et d'un second élément (32) est assemblée à l'aide d'un outil (1) et d'un rivet (5) en vue du soudage par friction-malaxage par points. La partie de chevauchement (30) est formée par la disposition du premier élément (31) du côté duquel l'outil (1) est inséré par pression en premier, et par la disposition du second élément (32) du côté duquel l'outil (1) est inséré par pression en dernier. Une partie traitée par friction-malaxage (4) est formée dans la partie de chevauchement (30) par l'insertion par pression de l'outil (1) dans la partie de chevauchement (30) et par réalisation d'une friction-malaxage. Le rivet (5) est inséré par pression dans la partie traitée par friction-malaxage (4) du côté premier élément (31). 摩擦攪拌点接合用のツール（１）とリベット（５）とを用いて、第１部材（３１）及び第２部材（３２）の重なり部（３０）を接合する。第１部材（３１）をツール（１）が最初に圧入される側に、第２部材（３２）をツール（１）が最後に圧入される側に各々配置して、重なり部（３０）を形成する。ツール（１）を、重なり部（３０）へ圧入して摩擦攪拌を行うことで、重なり部（３０）に摩擦攪拌部（４）を形成する。第１部材（３１）側から摩擦攪拌部（４）にリベット（５）を圧入する。
