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.
