Abstract

[Problem] The purpose of the present invention is to provide a spiral gasket which is less affected by the thermal degradation of the material under high temperature and high pressure conditions than conventional products and which therefore maintains consistent sealing performance for a long period of time. [Solution] A spiral gasket (1) has a seal section (5) formed by winding a metallic hoop material (3) having a bent section (2) in a cross-section thereof, the metallic hoop material (3) being wound in a spiral shape so that the bent section (2) of each winding is superposed on each other, the seal section (5) having a filler material (4) disposed in the radial gap between the windings of the metallic hoop material (3). The spiral gasket (1) is characterized in that at least a part of the filler material (4) in the spiral direction is configured from non-ferrous metal having higher deformability than the metallic hoop material (3).
