The present invention provides a metal resin complex having high gas sealing performance. An aluminum alloy structure having a shape that winds the periphery of a copper electrode (63) is produced at first, the winding aluminum alloy is closely adhered to the copper electrode (63), and the aluminum alloy is subjected to a pressing or forging process to allow the aluminum alloy to dig into the copper electrode (63). The copper electrode (63) is then processed mechanically into a predetermined shape, thereby producing the copper electrode (63) having the aluminum alloy member (61a) attached thereto. Subsequently, three members, i.e., an aluminum electrode (62), the copper electrode (63) having the aluminum alloy member (61a) attached thereto, and an aluminum alloy lid (61), are subjected to an NMT or NMT2 surface treatment, the three members are inserted into an injection molding mold, and a thermoplastic resin composition (64) which comprises a PPS resin is ejected, whereby a lithium ion battery lid (60) is produced. |
