Patent ID: 8758866

Claim:
A process for producing a composite of metal and resin comprising: a metal part composed of a metal and a resin part composed of a resin bonded together, which comprises: arranging the metal part; feeding a discharging gas into a plasma apparatus, the discharging gas including an organic substance including anyone of an acrylic acid and allylamine; generating a plasma containing a radical that activates the organic substance and the discharging gas; contacting the metal part with the plasma containing the activated organic substance and imparting a polar functional group onto a surface of the metal part, the polar functional group imparted onto the surface of the metal part including anyone of an unsaturated carboxyl group and an unsaturated amino group; preparing a molding material by blending the resin with an adhesiveness modifier containing an adhesive functional group which interacts with the polar functional group imparted onto the surface of the metal part, the adhesive functional group including anyone of an epoxy group, a carboxyl group, an amino group and a hydroxyl group; and forming the molding material on the surface of the metal part, wherein the polar functional group imparted on the surface of the metal part interacts with the adhesive functional group of the adhesive modifier contained within the molding material and bonds the metal part and the resin part.
