PURPOSE:To obtain the titled composition capable of keeping electrical conductivity even at high temperature, having excellent age stability and moldability and suitable for electronic apparatuses, etc., by using electrically conductive fiber in combination with a low-melting metal as electrically conductive fillers and compounding the fillers with a flux and a phosphorus-based antioxidant. CONSTITUTION:The surface of an electrically conductive filler composed of (A) electrically conductive fiber having a diameter of 8-100mum (e.g. copper filament or brass filament) (5-80wt.% based on the whole composition), (B) a low-melting metal (e.g. soldering alloy composed mainly of Sn or Sn-Pb) (5-30wt.% based on the component A) and (C) a flux (e.g. stearic acid) 0.1-5wt.% based on the component (B) is coated with (D) a thermoplastic resin (e.g. polypropylene) containing 0.1-5wt.% phosphorous-based antioxidant to obtain integrated pellets, which are chopped to form the objective composition.
