Abstract
Abstract A flexible electrically conductive sheet includes a wove fabric of fibers including stainless steel fibers, the woven fabric being impregnated with a synthetic resin material. Portions of the stainless steel fibers are exposed on surfaces of the synthetic resin material. By bringing an electrostatically charged object into contact with the exposed stainless steel fibers, the charged static electricity can be removed.
