To make it possible to partially impart brilliance without using a rare metal such as indium, in a radar cover.SOLUTION: A radar cover 10 comprises: a transparent member 11; and a base member 13 arranged on a back side of the transparent member 11 and visible through the transparent member 11. A back surface of the transparent member 11 is locally provided with a rough surface region Ra having a surface roughness larger than that of other regions on a back surface of the transparent member 11. The radar cover further comprises: translucent films 12 arranged between the rough surface region Ra and the base member 13, and having a refractive index different from that of the transparent member 11.SELECTED DRAWING: Figure 2
【課題】レーダカバーにおいて、インジウム等の希少金属を用いることなく、部分的に光輝性を付与可能とする。【解決手段】透明部材11と、透明部材11の背面側に配置されて透明部材11を介して視認可能なベース部材13とを備えるレーダカバー10であって、透明部材11の背面に対して、透明部材11の背面の他の領域よりも表面粗さが大きな粗面領域Raが局所的に設けられ、粗面領域Raとベース部材13との間に配置されると共に透明部材11と屈折率が異なる透光フィルム12を備えている。【選択図】図2
