    • An electromagnetic wave absorber having an excellent electromagnetic wave absorption characteristic in 5 to 6 GHz band. The electromagnetic wave absorber has a matrix and powder filled in the matrix. The particles of the powder have electrical conductivity at least in surface regions thereof and have a particle diameter of 3 to 20 μm as expressed by D50 value. A volumetric ratio (V) in which the powder is filled in the matrix is set such that a standardized value expressed as a value obtained by dividing a complex relative permeability (μ″) of the electromagnetic wave absorber in a frequency band to be absorbed thereby by the volumetric ratio (V) is constant as far as the particle diameter of the powder used, as expressed by the D50 value, is within the range of 3 to 20 μm.
    • 5〜6GHz频带的电磁波吸收特性优异的电磁波吸收体。 电磁波吸收体具有填充在基质中的基质和粉末。 粉末的颗粒至少在其表面区域具有导电性,并且具有由D 50值表示的3至20μm的颗粒直径。 将粉末填充在基质中的体积比(V)设定为表示为通过将电磁波吸收体的复数相对磁导率(mu“)除以频率吸收而得到的值的标准化值 因此通过DAL 50值表示的所用粉末的粒径的体积比(V)是恒定的,在3〜20μm的范围内。
