Radio wave absorber

Abstract

A radio wave absorber includes a conductor layer as a first conductor, a dielectric layer, and a pattern layer as a second conductor. The dielectric layer includes one or more dielectric members. The pattern layer has conductor patterns arranged regularly. The conductor layer, the dielectric layer, and the pattern layer are sequentially stacked in a stacking direction such that the dielectric layer is interposed between the conductor layer and the pattern layer. The second conductor includes a conductive portion which is electrically conductive. The dielectric layer includes a conductor-overlapping portion that is overlapped with the conductive portion in the stacking direction, and a non-overlapping portion that is not overlapped with the conductive portion in the stacking direction. The dielectric layer has different path-lengths for radio waves in the stacking direction between the conductor-overlapping portion and the non-overlapping portion.
