Abstract: Electromagnetic wave shielding material including a conductive fiber web with multiple pores and a heat dissipation unit provided in at least some pores that is so excellent in flexibility, elasticity, and creasing/recovery that it can be changed in shape freely and brought in complete contact with a surface where the material is to be disposed even if the surface has a curved shape, uneven portions, or stepped portions, thus exhibiting excellent electromagnetic wave shielding performance and prevent deterioration thereof despite various shape changes. Since heat dissipation performance is excellent, heat generated in an electromagnetic wave source can be rapidly conducted and released. Even if parts are provided in a narrow area at high density, the material can be brought in close contact with mounted parts by overcoming a tight space between the parts and a stepped portion. The invention is employed for light, thin, short, and small or flexible devices.
