Abstract
Provided is a method for joining two dissimilar metal plates having different volume resistivity to increase joint strength of the metal plates. The method includes: overlapping a first metal plate including a first metal and a second metal plate including a second metal, the second metal having volume resistivity higher than the first metal and being different from the first metal, and bringing a pair of electrodes into contact with a surface of an overlapped portion of the first metal plate that is overlapped with the second metal plate; and applying current between the electrodes so as to melt the first metal present at a current-flowing region of the overlapped portion due to heat generated by resistance to form an intermetallic compound of the first and the second metals between the first and the second metal plates and join the first and the second metal plates via the intermetallic compound.
