This invention relates to a packing used in sealing two members. As the packing material, by using a material having the surface of a flexible graphite sheet cut to a width of less than 5 mm with fibers, or a material prepared by laminating a flexible graphite sheet cut to a width of less than 5 mm with at least one of reinforcing fiber of foil material, and covering its surface with fibers, or a material prepared by impregnating a principal component composed of flexible graphite particles with at least one of short fiber, rubber, resin or lubricant to form a bar-like structure and covering its surface with fibers, a packing material which can be either twisted or braided is obtained. By fabricating a packing by using any one of such packing materials, a cord-like packing is obtained without having to produce many packings matched to the dimensions of the members.
