To provide a radio wave transmission cover capable of enhancing degree of freedom of design.SOLUTION: A radio wave transmission cover is arranged in a radio wave path of a radio wave radar device 99, and includes a cover body having a transparent first cover layer 20 made of a resin material, a base material layer 50 formed of the resin material and provided on a rear surface of the first cover layer 20, and colored intermediate layers 30, 40 provided between the first cover layer 20 and the base material layer 50. At a portion between an outer peripheral edge and a central portion of the cover body, an opening 70 is provided that penetrates at least the base material layer 50 and the intermediate layers 30, 40 in a thickness direction and opens to a rear surface of the base material layer 50.SELECTED DRAWING: Figure 2 【課題】意匠の自由度を高めることのできる電波透過カバーを提供する。【解決手段】電波透過カバーは、電波レーダ装置９９の電波の経路内に配置されており、樹脂材料により形成された透明な第１カバー層２０と、樹脂材料により形成され、第１カバー層２０の後面に設けられた基材層５０と、第１カバー層２０と基材層５０との間に設けられた有色の中間層３０、４０と、を有するカバー本体を備え、カバー本体の外周縁と中央部との間の部分には、少なくとも基材層５０と中間層３０、４０とを厚さ方向に貫通するとともに基材層５０の後面に開口する開口部７０が設けられている。【選択図】図２
