Title: METAL RESIN JOINING APPARATUS
Abstract:
A metal resin joining apparatus according to the present invention joins a thermoplastic resin plate (12) to a metal plate (13) by melting the resin plate (12) abutted against the metal plate (13) through heating by one-side resistance heat generated from the exposed surface of the metal plate (13). The metal resin joining apparatus is provided with: a center electrode (24a) that is abutted against the metal plate (13); an outer-peripheral electrode (24b) that is abutted against the metal plate (13) so as to annularly surround the center electrode (24a) and that causes a current to flow between the outer-peripheral electrode (24b) and the center electrode (24a) via the metal plate (13), wherein the outer-peripheral electrode (24b) is formed from a metallic material having higher electrical resistance than the center electrode (24a).
