<p>PROBLEM TO BE SOLVED: To provide a radio wave absorber excellent in electromagnetic wave absorption characteristics in not only vertical incidence but also oblique incidence and also low in total length, and a radio wave dark room using the radio wave absorber.SOLUTION: A radio wave absorber includes: a plurality of first radio wave absorption parts 2 comprising an electromagnetic wave loss material, having almost equal height with each other and having a shape of a pyramid, a frustum, a wedge body or a shape similar to them, as a whole; and a plate like second radio wave absorption part 3 comprising an electromagnetic wave loss material. The first radio wave absorption parts 2 are disposed on a plane, and the second radio wave absorption part 3 is disposed in parallel with the plane where the first radio wave absorption parts 2 are disposed.</p> |
