The friction stirring is performed to the butted portion while rotating the stirring pin at a predetermined rotational speed. The rotary tool is made to leave the first metal member in the leaving section when the rotary tool is moved to the ending position while gradually decreasing a rotational speed of the stirring pin from the predetermined rotational speed.
