Abstract:
The present invention relates to an electromagnetic wave absorbing body which is a sheet-like electromagnetic wave absorbing body in which particles including a soft magnetic material are dispersed in a matrix including a non-metal material, in which the electromagnetic wave absorbing body satisfies a relationship: α≥⅕, in which α is a parameter given by Equation (1): α=Ad(εμ)0.5/(μ″+ε″μ/ε), in which d is a thickness of the electromagnetic wave absorbing body, ε, ε″, μ, and μ″ are a permittivity of the electromagnetic wave absorbing body, a loss term of ε, a permeability of the electromagnetic wave absorbing body, and a loss term of μ, respectively, and A is equal to 8×104/π(Ω/m).
