A composite material comprising a resin other than polyamide resin and a layered silicate dispersed therein, said layered silicate having a layer thickness of 7 to 12 ANGSTROM and an interlayer distance of 30 ANGSTROM or above. Owing to the layered silicate uniformly dispersed in the resin matrix, the composite material is superior in mechanical characteristics and heat resistance. It also has good water resistance and chemical resistance.
