Electromagnetic interference suppressing material

Abstract

An electromagnetic interference suppressing material includes: a base material containing at least one selected from the group consisting of an organic substance and an inorganic substance; and a carbon composite material. The carbon composite material includes at least one selected from the group consisting of a core-shell particle and a core-shell connected body, where the core-shell particle includes an inorganic particle in which a surface of the inorganic particle is coated with a coating layer composed of graphene having an average number of layers of 4 or less, and the core-shell connected body includes a connected body of inorganic particles in which a surface of the connected body of inorganic particles is coated with a coating layer of graphene having an average number of layers of 4 or less, and the electromagnetic interference suppressing material has a volume resistance of 103 Ω·cm or more.
