To provide a front grille which can improve transmission/reception performance of a radar device.SOLUTION: A panel material, which constitutes a design surface, includes a first region where electric waves emitted from an antenna surface are directly incident, and a second region which is a region other than the first region, and is positioned on a front side in an electric wave emission direction with respect to the antenna surface. In the second region, one or both of a recess, which is recessed in a thickness direction of the panel material, and a protrusion, which protrudes in the thickness direction, are formed on at least one of a front face and a rear face of the panel material. One or both of the recess and the protrusion constitute a part of a pattern formed on the design surface.SELECTED DRAWING: Figure 1

    【課題】レーダ装置の送受信性能を向上させることが可能なフロントグリルを提供する。【解決手段】意匠面を構成するパネル材が、アンテナ面から出射された電波が直接入射する第1領域と、第1領域以外の領域であってアンテナ面よりも電波の出射方向前方側に位置する第2領域とを含む。第2領域では、パネル材の表面及び裏面の少なくとも一方に、パネル材の厚さ方向に凹んだ凹部及び該厚さ方向に突出した凸部の一方または両方が形成されている。当該凹部及び凸部の一方または両方は、意匠面に形成された模様パターンの一部を構成している。【選択図】図1
