A gland packing is braided in a state where, in crossing angles of yarns which are exposed on four side surfaces of a string-like member, crossing angles in adjacent side surfaces of the four side surfaces are different from ch other. The string-like member is looped so that the crossing angle on the side surface in the four side surfaces, the side surface being to function as an inner circumferential surface, is larger than the crossing angles on side surfaces which are to function as side circumferential surfaces adjacent to the inner circumferential surface. |
