Abstract
In a friction agitation joining method for joining two plate-shaped joining members butted against each other with a level difference formed at upper surface sides thereof by a joining tool having a probe rotatable about a rotation axis thereof, the butted joining members are arranged so as to be inclined to a horizontal plane with one of the joining members having a higher upper surface level positioned at a lower side and the other at a higher side. Then, the rotating probe is inserted into a butted portion of the joining members or the vicinity thereof in a state that the rotation axis is parallel to a vertical plane extending along the butted portion. Then, the probe is moved relative to the joining members along the butted portion with the probe inserted into the butted portion or the vicinity thereof.
