Abstract
A method for joining dissimilar metals according to the embodiment is a method for butt-joining, using frictional heat, a first member having a plate shape and containing first metal and a second member having a plate shape and containing second metal having a melting point higher than that of the first metal. The method for joining dissimilar metals includes: overlapping an end portion of the second member on an end portion of the first member; and pressurizing the second member toward the first member by bringing a rotating joining tool having a protruding portion at a tip end into contact with an overlapping portion of the second member with the first member. When the second member is pressurized toward the first member, the tip end of the rotating joining tool is not in contact with the first member.
