PURPOSE:To obtain a composite material suitable as electrically conductive material or electromagnetic wave shielding material, having excellent mechanical properties and high electric properties, by packing a polymer containing an electrically conductive filler to pores of porous polymer material having open pores. CONSTITUTION:A polymer B containing 10-95wt.% electrically conductive filler is packed into pores of porous material of a polymer A having open pores with 0.05-10mm pore diameter and 5-95vol.% voids to give a composite material. The composite material is obtained by packing a liquid monomer or prepolymer of the polymer B containing an electrically conductive filler to the pores of porous material of the polymer A, polymerizing or crosslinking and solidifying the polymer B. Polyethylene, polystyrene, etc., are used as the polymer A and polymethyl methacrylate, etc., are the polymer B.
