PROBLEM TO BE SOLVED: To provide a radio wave absorber where radio wave absorbing characteristic in GHz band is superior, design for a thin type is easy and specific bandwidth can be made greater than or equal to that of the conventional one. SOLUTION: In this radio wave absorber, a radio wave absorbing layer 1 and a radio wave reflecting layer 3 are laminated. In the radio wave absorbing layer 1, metal material composed of 0.1-5 wt.% V, 20-70 wt.% Co and 25-79.9 wt.% Fe is made powder whose grain diameter is 1-100 μm and mixed and dispersed in base composed of synthetic resin material. The radio wave reflecting layer 3 is formed of, e.g. an aluminium plate as conducting substance. |
