PROBLEM TO BE SOLVED: To provide a metal/resin compound object constituted by integrally joining a metal shaped article and a thermoplastic resin composition, having strong bonding properties and massproductivity and capable of being freely designed in shape and structure, and its manufacturing method. SOLUTION: The metal shaped article 1 having a microporous surface layer is obtained from a metal. For example, an aluminum alloy shaped article, a magnesium alloy shaped article or a titanium alloy shaped article is subjected to anodic oxidation to form a porous layer on its surface. This shaped article having the porous layer is immersed in an aqueous solution having a water-soluble amine type compound dissolved to occlude the amine type compound into the pores of the porous layer. This metal shaped article is inserted in an injection mold and, when a PBT or PPS resin composition is injected in the mold, the metal shaped article 1 and the PBT or PPS resin composition 2 are strongly joined to become the integrated compound object 4.
