Beschreibung
Zusammenfassung:	The present invention includes: a preparation process configured to provide a first metal member including an end portion with a vertical face, and a second metal member including an end portion with an inclined face, a higher melting point and a smaller plate thickness than the first metal member; a butting process configured to butt the end portions of the first metal member and the second metal member against each other and form a butted portion with a V-shaped gap; and a joining process configured to join the first metal member and the second metal member together by inserting the rotating rotary tool from only a front face of the first metal member and relatively moving the rotary tool along the butted portion while only the stirring pin is in contact with at least the first metal member.
