Zusammenfassung:	An electromagnetic wave absorber and an electromagnetic wave anechoic room using the absorbers. The electromagnetic wave absorber has improved electromagnetic wave absorption characteristics at high frequencies in spite of having a hollow structure. The electromagnetic wave absorber includes a hollow shell with a bottom that is a rectangle. A part of a surface of the hollow shell and an outer face of a planar extension lie in planes that are not parallel to any side of the rectangle. At least the plane that is not parallel to any side of the rectangle is included in a surface of an electromagnetic wave absorption member.
