図1に示すように、本実施形態に係る車載用アンテナ装置20は、車両10のルーフ11に取り付けられる。このような車載用アンテナ装置20は、シャークフィン型のアンテナ装置として知られている。以下、車載用アンテナ装置20を、単にアンテナ装置20と示す。
図5は、クリアランスL1と、回路部28の温度との関係を示している。クリアランスL1がゼロ、すなわち、回路部28及び基板24における回路部28の実装部位の裏面部位に、対応する厚肉部30aがそれぞれ接触した状態で、回路部28の温度は約70℃であった。また、クリアランスL1が長くなるほど、回路部28の温度は高くなり、例えばクリアランスL1が0.5mmで、回路部28の温度は約78℃であった。そして、厚肉部30aなしの状態で、図5に破線で示すように、回路部28の温度は約90℃であった。この結果からも、回路部28が筺体30の厚肉部30aに直接的に接触し、これにより、回路部28と筐体30との間に、熱伝達経路が形成されることで、回路部28の温度を低下させることができることが明らかとなった。換言すれば、回路部28の性能が低下するのを抑制することができることが明らかとなった。
