PROBLEM TO BE SOLVED: To provide a radio wave absorber non-inflammable with thin thickness and excellent in oblique incidence characteristics of radio wave and low in cost. SOLUTION: The radio wave absorber is formed of a hardened body containing cement powder or silica powder as a main raw material, and natural sandy titanic iron ore is used as a radio wave absorbing material for a part of aggregate mixed in the cement and silica. After mixing and forming, the hardened body is formed by a calcium silicate hydrate, and radio wave in a range of frequency band 2-7 GHz is absorbed. COPYRIGHT: (C)2006,JPO&NCIPI
