Abstract
A metal-resin joining device joins a thermoplastic resin plate () to a metal plate () by melting the resin plate () in contact with the metal plate () through heating an exposed face of the metal plate () by one-sided resistive heating. The metal-resin joining device has a center electrode () that is brought in contact with the metal plate () and a peripheral electrode () that is brought in contact with the metal plate () to annularly surround the center electrode () and to which a current flows from the center electrode () via the metal plate (), wherein the peripheral electrode () is made of a metal material having a higher electrical resistance than the center electrode ().
