Disclosed is a resin-metal bonded body of an aluminum metal member and a thermoplastic resin member, which has improved bonding strength and good durability. Also disclosed is a method for producing such a resin-metal bonded body. Specifically disclosed is a resin-metal bonded body which is obtained by bonding an aluminum metal member with a thermoplastic resin member. In this resin-metal bonded body, the aluminum metal member and the thermoplastic resin member are bonded together by an anodic oxide coating having a film thickness of 70-1500 nm or an anodic oxide coating having a triazine thiol in the inner and upper portions. The anodic oxide coating has an infrared absorption spectrum peak intensity ascribed to OH group at 0.0001-0.16.

Disclosed is a resin-metal bonded article which is improved in adhesion between a copper component and a PPS or PBT resin. Also disclosed is a method for producing such a resin-metal bonded article. The resin-metal bonded article is obtained by bonding the resin component onto the surface of the copper component through a copper component bonding surface where there is copper oxide in the following range: 10%&#x2266;CuO/(CuO+CuO)&#x2266;75%. Preferably, this resin-metal bonded article further contains a triazine thiol derivative in the resin-component-side bonding surface of the copper component.
