To achieve improvement in the snow melting efficiency and the appearance with a simple structure.SOLUTION: An electric wave transparent cover 20 is applied to a vehicle 10 to which a millimeter wave radar device 12 transmitting a millimeter wave 13 to the outside of the vehicle and receiving the millimeter wave 13 irradiated to an object outside the vehicle and reflected therefrom is incorporated, and is arranged on the front side of the millimeter wave radar device 12 in the transmission direction of the millimeter wave 13. The electric wave transparent cover 20 includes: a base material 21 which consists of a single member formed of an opaque resin material and having the transmissivity of the millimeter wave 13; and a heating sheet 31 which is arranged on the rear side of the base material 21 in the transmission direction. The heating sheet 31 includes: a sheet-like joint material 32 in which at least a front surface in the transmission direction is constituted by a front adhesive surface 34; and a heater wire 36 which is embedded and routed on the front adhesive surface 34 of the joint material 32 and generates heat by the electric conduction, and is fixed on the base material 21 by being stuck to the rear surface of the base material 21 in the transmission direction on the front adhesive surface 34.SELECTED DRAWING: Figure 3

    【課題】氷雪の融解効率及び外観の向上を、簡単な構造で実現する。【解決手段】電波透過カバー20は、ミリ波13を車外へ向けて送信し、かつ車外の物体に当たって反射されたミリ波13を受信するミリ波レーダ装置12が組み込まれた車両10に適用され、ミリ波13の送信方向におけるミリ波レーダ装置12の前方に配置される。電波透過カバー20は、不透明な樹脂材料により形成され、かつミリ波13の透過性を有する単一の部材からなる基材21と、上記送信方向における基材21の後側に配置された加熱シート31とを備える。加熱シート31は、上記送信方向における少なくとも前面が前接着面34により構成されたシート状の接合材32と、接合材32の前接着面34上に埋め込んで配線され、かつ通電により発熱するヒータ線36とを備え、前接着面34において、上記送信方向における基材21の後面に貼り合わされることにより同基材21に固定されている。【選択図】図3
