(57) Abstract: A resin-expanded graphite sheet that can be used as a gasket material having excellent heat resistance and sealing properties, and a method for manufacturing an inexpensive resin-expanded graphite sheet are provided. A resin-containing expanded graphite sheet in which a resin containing a dihydrobenzoxazine ring in a molecule is fixed to the surface of an expanded graphite sheet and a resin containing a dihydrobenzoxazine ring in a molecule are formed on the surface of the expanded graphite sheet. After adhering, the resin is heated to soften or melt the resin, and the resin is fixed to the expanded graphite sheet. |
