PROBLEM TO BE SOLVED: To provide a production method of a radar cover capable of reducing a formation material of a metallic thin film, concerning a production method of a radar cover including a metallic thin film having radio wave transmissivity.SOLUTION: There is provided a production method of a radar cover for forming a metallic thin film 12c with a structure having a plurality of island parts arranged at a clearance, on the surface of a substrate 12a by vacuum deposition. The production method of a radar cover has a metallic thin film formation step for forming a metallic thin film 12c by adjusting by an ion beam, the ratio between a size in a direction along the surface of the substrate 12a of the island parts and a size in a direction orthogonal to the surface of the substrate.SELECTED DRAWING: Figure 5 【課題】電波透過性を有する金属薄膜を備えるレーダカバーの製造方法において、金属薄膜の形成材料を削減可能なレーダカバーの製造方法の提供。【解決手段】隙間を空けて配置される複数の島部を有する構造の金属薄膜１２ｃを真空蒸着により基材１２ａの表面に形成するレーダカバーの製造方法。島部の基材１２ａの表面に沿う方向の寸法と基材の表面と直交する方向の寸法との比をイオンビームにより調整して金属薄膜１２ｃを形成する金属薄膜形成工程を有するレーダカバー前記蒸着材料が、Ｉｎであるの製造方法。【選択図】図５
