Provided is a spiral wound gasket that makes it less likely that gaps that are in communication with each other in a spiral shape will remain between layers of a filler member exposed at a gasket face in a state before the gasket is clamped and that is capable of exhibiting sufficient sealability for flanges provided at pipe joints. The present invention provides a spiral wound gasket in which a laminate of a hoop member made of metal and a filler member is wound around an opening and integrated, and which has gasket faces at respective end portions, wherein, at each of the gasket faces, an end portion of the filler member protrudes past an end portion of the hoop member, and the gasket faces have a surface roughness Rz of 30 μm to 200 μm.
