Abstract

Abstract The invention provides antistatic clothing suitable for wear in a room which is kept clean. The clothing, such as working clothes, work shoes, etc., manufactured from a cloth having parallel electroconductive fibers woven therein, features the incorporation of an electroconductive material at overlapped or butt-joined seams between the pieces of cloth forming the clothing to ensure a perfect electrostatic connection of all the pieces of the clothing to minimize static charging on both the clothing and the wearer's body while preventing dust from gathering on the clothing to avoid dust from becoming a cause of problems such as electrostatic breakdown of circuit elements in a semiconductor integrated circuit production plant.
