Abstract
A metal-resin joining device joins a thermoplastic resin plate (12) to a metal plate (13) by melting the resin plate (12) in contact with the metal plate (13) through heating an exposed face of the metal plate (13) by one-sided resistive heating. The metal-resin joining device has a center electrode (24a) that is brought in contact with the metal plate (13) and a peripheral electrode (24b) that is brought in contact with the metal plate (13) to annularly surround the center electrode (24a) and to which a current flows from the center electrode (24a) via the metal plate (13), wherein the peripheral electrode (24b) is made of a metal material having a higher electrical resistance than the center electrode (24a).
