Abstract: The present invention provides a metal coated fiber with excellent coating strength and corrosion resistance, and a conductive resin composition with excellent conductivity. A feature of a metal coated fiber of the present invention is that following provision of a metal coating on the surface of the fiber, heat treatment is conducted at a temperature greater than the crystallization temperature but less than the melting temperature of the fiber. Gradual cooling is preferably performed following the heat treatment. Furthermore, a conductive metal coating may be provided as the metal coating, and an additional corrosion resistant metal coating then laminated onto the surface of the conductive metal coating. In addition, a feature of a conductive resin composition of the present invention is that metal coated short fibers, formed by providing a conductive metal coating on the surface of a substrate fiber formed from a synthetic resin and then conducting heat treatment, are mixed into a substrate resin.

Abstract: A white conductive fiber is manufactured at an inexpensive cost having superior conductivity and high degree of whiteness, in which a metal coating plated on the fiber has superior adhesiveness. A method for manufacturing the white conductive fiber comprises the steps of mounting a wound fiber body formed by winding a continuous fiber to the fixing shaft, a step of flowing a plating solution from the fixing shaft to a plating bath via the wound fiber body so as to infiltrate the plating solution into the wound fiber body, and a step of performing electroless plating of silver, platinum, or the like on the fiber material while the plating solution flows.
