Abstract: A composition is composed mainly of: a component (I) (which is at least one selected from polyether ketone, polyether ether ketone, and polyether ketone ketone); a component (II) (which is polyphenylene sulfide); and, additionally if necessary, a component (III) (which is at least one selected from polyether imide, polyimide, polyamide imide, and polysulfone resins) and (IV) an inorganic filler. The composition is obtained using a conventional melt-kneading machine, for example, a single screw or twin screw extruder, Banbury mixer, or kneader in accordance with the melt-kneading method corresponding to the kneading machine. The resin composition for metal bonding has excellent metal bonding properties, and is applicable for use in automobile parts that require the composition to be bonded with metal and in electronic products such as laptop computers and mobile phones.
