There is provided a composite composed mainly of graphite and clay and having the structure of graphite laminated with and/or impregnated with clay. The composite is produced by subjecting an exfoliated graphite sheet or film or a molding therefrom to coating with and/or immersion in a clay dispersion liquid with clay particles dispersed therein, or by laminating together of an exfoliated graphite sheet and/or film and a sheet and/or film composed mainly of clay. Further, a gasket or packing is produced by molding the composite.
