To provide a radar device capable of suppressing floor noises caused by high-frequency IC while dissipating the heat generated by the high-frequency IC.SOLUTION: A radar device 100 includes a circuit board 1, an MMIC 2, a shield case 3, a coating film 4, and a gel in shield 6. The MMIC 2 is attached to the circuit board 1. The shield case 3 accommodates the MMIC 2. The coating film 4 is formed at least in a part of the inner face of the shield case 3. The coating film 4 has radio wave absorption performance and heat dissipation performance. The gel in shield 6 covers at least a part of the MMIC 2 and in contact with at least a part of the coating film 4. The gel in shield 6 has a heat dissipation performance.SELECTED DRAWING: Figure 1 【課題】高周波ＩＣで発生した熱を放散するとともに、高周波ＩＣに起因するフロアノイズを抑制することができる、レーダ装置を提供する。【解決手段】レーダ装置１００は、基板１と、ＭＭＩＣ２と、シールドケース３と、塗膜４と、シールド内ゲル６と、を備える。ＭＭＩＣ２は、基板１に取り付けられる。シールドケース３には、ＭＭＩＣ２が収容される。塗膜４は、シールドケース３の内面の少なくとも一部に形成される。塗膜４は、電波吸収能及び放熱性を有する。シールド内ゲル６は、ＭＭＩＣ２の少なくとも一部を覆い、塗膜４の少なくとも一部と接する。シールド内ゲル６は、放熱性を有する。【選択図】図１
