Abstract
A different material joining method sandwiches, with electrodes, a first joining member and a second joining member lower in melting point than the first member, applies pressure and electricity to them, and joins them in preset joint parts. The method includes forming a discontinuous abutting part beforehand in the joint part of at least one of the two members. The two members abut onto the abutting part in a discontinuous state. The method includes melting the second member by sandwiching the joint parts with the electrodes and applying pressure and electricity on the joint parts in a state where the two members abut onto each other in the joint parts while the abutting part is included. The method includes welding both the members by bringing a melting material of the second member into interface joining with a surface of the first member toward the second member.
