An object of the present invention is to provide an electromagnetic wave attenuation film that is less likely to shift an absorption peak frequency or change in frequency characteristics and angle characteristics over time, and has light transmission and image shielding properties, simply and at a low cost. An electromagnetic wave absorption film of the present invention includes a dielectric substrate having a front surface and a back surface, a thin film conductive layer disposed on the front surface of the dielectric substrate, and a mesh-like flat plate inductor disposed on the back surface of the dielectric and formed of thin conductive thin films, The thin-film conductive layer includes a plurality of conductive elements. Further, the conductive elements may be arranged periodically, and the following expression (4) may be satisfied, where T is the thickness of the conductive elements and d is the skin depth. Furthermore, the mesh forming the...
