<P>PROBLEM TO BE SOLVED: To easily control radio wave absorption performance without causing any problems of weight burdens on an object structure or workability. <P>SOLUTION: The radio wave absorber includes a radio wave absorbing layer 20 in which radio wave absorbing materials 21 are arranged in stripes on the surface of a metal frame 1 at an interval from each other by arranging a plurality of foamed urethane resins 22 in stripes at positions securing a prescribed interval on the surface of the metal frame 1, then applying a liquid radio wave absorbing materials 21 with hardenability mutually between the foamed urethane resins 22, and applying a polyurethane resin material which is a top coating material with weathering ability respectively on the surface of the foamed urethane resins 22 and the surface of the radio wave absorbing materials 21 further. <P>COPYRIGHT: (C)2009,JPO&INPIT |
