▎ 摘　　要

NOVELTY - Electromagnetic interference suppressing material comprises a base material containing at least one chosen from organic substances and inorganic substances, and a powdered carbon material. The powdered carbon material is at least one chosen from a first shell-shaped body which is a hollow particle having one hole, and a second shell-shaped body that has a shape in which hollow particles are connected and has holes. The shell portions of the first shell-shaped body and the second shell-shaped body are made of graphene having an average number of layers of 4 or less. USE - The electromagnetic interference suppressing material is used as semiconductor element sealing material (claimed), radio wave absorber, noise suppression sheet, semiconductor sealing material, sealing sheet, and wire coating material. ADVANTAGE - The electromagnetic interference suppressing material has excellent electromagnetic wave absorption performance, electromagnetic interference suppression performance, and electromagnetic interference reduction performance.
