To provide a radio wave permeable cover with which it is possible to increase the freedom of design while securing sealability.SOLUTION: The radio wave permeable cover comprises a cover body including a transparent first cover layer 20 arranged in a radio wave path of a radio wave radar device 99 and formed with a resin material, a colored second cover layer 30 formed with the same resin material as said resin material and provided at the rear of the first cover layer 20, and a base layer 50 formed with a resin material different from said resin material and provided at the rear of the second cover layer 30. In a portion of the cover body between the circumferential edge and the center part is provided an opening 70 penetrating at least the base layer 50 and the second cover layer 30 in the depth direction and opened at the rear of the base layer 50, and around the opening 70 is provided a seal part 60 for sealing between the base layer 50 and the second cover layer 30 due to the fact that the base layer 50 and the second cover layer 30 are joined together by having a convex-concave relation.SELECTED DRAWING: Figure 2 【課題】シール性を確保しつつ、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、前記樹脂材料と同一の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有色の第２カバー層３０と、前記樹脂材料とは異なる樹脂材料により形成され、第２カバー層３０の後面に設けられた基材層５０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と第２カバー層３０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が設けられており、開口部７０の周囲には、基材層５０と第２カバー層３０とが凹凸の関係を有して接合されることで基材層５０と第２カバー層３０との間をシールするシール部６０が設けられている。【選択図】図２
