An expanded graphite knitting yarn according to the present invention is covered or bound and covered with a reinforcing material made of a braided body such as stainless steel line members, before an outer periphery of an expanded graphite tape having a predetermined width, which has been subjected to a twisting process, is braided. Therefore, an amount of the expanded graphite particles exfoliated from ends of the expanded graphite tape in the twisting process can be significantly reduced. Moreover, this can prevent the expanded graphite particles from being exfoliated from the end of the expanded graphite tape in a braiding process. Furthermore, the plural expanded graphite knitting yarns are put together and subjected to either braiding or twisting process, thereby forming a gland packing. This can enhance a sealing property and a pressure resistance property of the gland packing.
