Abstract
An electrically conductive thermoplastic resin monofilament having a high mechanical strength and an excellent electrical conductivity is produced. This monofilament containing an electrically conductive carbon black is produced through extrusion, cooling, aging, and orientation steps, the temperature of the monofilament in the orientation step is within the range of from 60.degree. C. to 5.degree. C. less than the melting point of the thermoplastic resin, and orientation is carried out at a stretching strain rate of 5000%/min or less. Also in the aging step the temperature is optionally kept constant.
