Beschreibung
Zusammenfassung:	The present invention improves the handling properties of a rubber-only gasket. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the carrier sheet is provided with an air intake port for introducing air between the carrier sheet and the gasket body when removing the gasket body from the carrier sheet. Furthermore, the location on the carrier sheet at which the gasket body overlaps when seen from a planar view is provided with a three-dimensionally shaped gasket-holding part that deforms according to the external shape of the gasket body, and retains part of the gasket body in the thickness direction thereof. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.
