Abstract
An electromagnetic wave absorber includes a dielectric layer, a divided conductive film layer and an electromagnetic wave reflective layer, wherein a ratio of thickness 'd' and wavelength 'λ' satisfies a condition of [0.01≦d/λ0.03], weight per unit area of the electromagnetic wave absorber falls within a range of 1000 g/mand 3000 g/m. The divided conductive film layer is configured such that each side's length of conductive films is dimensioned within a range of 0.5 mm and 4.8 mm and arrangement distance between adjoining conductive films is taken within a range of 0.01 mm and 3 mm.
