To provide a technology that solves the problem that could occur when installing an absorption element and reduces bearing detection errors by a radar device.SOLUTION: A radar device 1 comprises an antenna unit 341, cover units 32, 8, and a radio wave suppression unit 36. The antenna unit includes an antenna surface 35 on which one or more antennas that radiate a radio wave are installed, and is constituted so as to radiate an object radio wave of a predetermined frequency band. The cover unit is constituted so as to be installed at a position where the object radio wave passes through. The radio wave suppression unit is formed integrally with the cover unit in a range of an outer surface of the cover unit on an outer surface of the cover unit in a detection range outside area 40 that is an area outside a range of detection angles of the antenna unit, and includes conductive parts 50 having electric conductivity and non-conductive parts 60 not having electric conductivity.SELECTED DRAWING: Figure 3 【課題】吸収要素を設置する際に生じ得る課題を解決し、レーダ装置による方位検知誤差を低減する技術を提供する。【解決手段】レーダ装置１は、アンテナ部３４１と、カバー部３２、８と、電波抑制部３６と、を備える。アンテナ部は、電波を放射する１つ以上のアンテナが設置されたアンテナ面３５を含み、予め定められた周波数帯の対象電波を照射するように構成される。カバー部は、対象電波が透過する位置に設けられるように構成される。電波抑制部は、カバー部の外面のうち、アンテナ部の検知角度の範囲外の領域である検知範囲外領域４０にカバー部と一体に形成され、導電性を有する導電化部５０と導電性を有しない非導電化部６０と、を含む。【選択図】図３
