Aluminum resin bonded body and process for producing same

A process for producing an aluminum-resin bonded body, comprising:

• a film-forming step of forming an oxygen-containing film on a surface of an aluminum substrate formed of aluminum or an aluminum alloy;
• and
• a resin-molding step of forming a molded resin on the oxygen-containing film of the surface-treated aluminum substrate obtained in the film-forming step, by injection molding of a thermoplastic resin,
• to produce an aluminum-resin bonded body in which the aluminum substrate and the molded resin are bonded through intermediary of the oxygen-containing film,
• wherein the thermoplastic resin comprises a thermoplastic resin containing an element having an unshared electron pair in a repeat unit and/or an end.
