PROBLEM TO BE SOLVED: To provide thin type electromagnetic wave absorption material which is easy to work in molding by a simple method without depending on complex radio wave theory. SOLUTION: In the electromagnetic wave absorption material which has lamination structure of at least three layers, the material is characterized by including a metal thin film layer of at least one layer between at least two layers which contain conductive carbon material, or in the electromagnetic wave absorption material, the material is characterized by forming at least one couple of lamination structure of one metal thin film layer and one layer which contains conductive carbon material. Preferably, the material is characterized in that the conductive carbon material content layer and the metal thin film layer are integrated. More preferably, the material is characterized by including the conductive carbon material content layer between at least two layers of maintenance layer constituted of resin coating paper.
