PURPOSE:To form a conductive resin composition having excellent conductivity and being free from lowering in conductivity even at high temperatures, by coating the surface of a conductive filler with a flux-containing thermoplastic resin, pelletizing the resulting filler to form master pellets, and mixing these pellets with pellets of an antioxidant-containing thermoplastic resin. CONSTITUTION:This conductive resin composition is formed by coating the surface of a conductive filler comprising a conductive fiber and a low-melting metal with a thermoplastic resin containing a flux (C), cutting the product into pellets and mixing the obtained master pellets with pellets of a thermoplastic resin containing an antioxidant. A conductive resin molding can be obtained by injection-molding this composition at a temperature >= the melting point of the low-melting metal. A copper fiber is the most desirable as said conductive fiber. An example of said low-melting metal is a soldering alloy based on Sn or Sn-Pb. |
