PROBLEM TO BE SOLVED: To easily manufacture an electric wave transparent cover capable of suppressing thermal damage occurring in a transparent member during insert molding of a base material.SOLUTION: The electric wave transparent cover 10 is a cover disposed in a path of an electric wave of an electric wave radar device, and includes a transparent member 20 made of a resin material and a base material 50 that is made of resin material and formed on the rear surface side of the transparent member 20. The cover 10 also includes: a decorative layer 30 formed on the rear surface of the transparent member 20; and a reduction sheet 40 that is previously molded of a resin material, is disposed on the decorative layer 30 so as to cover the rear surface of the decorative layer 30, and reduces the heat transfer to the transparent member 20 side during insert molding of the base material 50.
【課題】基材のインサート成形時において透明部材に熱損傷が生じることを抑制することができる電波透過カバーを容易に製造することができる。【解決手段】電波透過カバー10は、電波レーダ装置の電波の経路内に配置されるカバーであって、樹脂材料からなる透明部材20と、樹脂材料からなり、透明部材20の後面側に形成された基材50と、を備える。また、カバー10は、透明部材20の後面に形成された加飾層30と、樹脂材料からなるとともに予め成形されてなり、加飾層30の後面を覆うように同加飾層30上に配置されて基材50のインサート成形時における透明部材20側への熱の移動を緩和する緩和シート40と、を備える。【選択図】図3
