To improve the transmission performance of a near-infrared ray while exhibiting a snow melting function.SOLUTION: A near-infrared sensor cover 31 comprises: a cover body part 37 formed in shape of a plate and arranged in a state where the thickness direction is matched to a direction in which near-infrared rays IR1, IR2 are transmitted and received, for covering a transmission unit 18 and a reception unit 19 of the near-infrared rays IR1, IR2; and a heater wire 44 for generating heat upon conduction of electricity and arranged at the rear side in the thickness direction of the cover body part 37. The heater wire 44 includes a plurality of straight wire portions 45 extending in parallel to each other and a plurality of connecting wire portions for connecting the ends of adjacent straight wire portions 45 to each other. An interval p1 of adjacent straight wire portions 45 is set to 3 mm to 10 mm, and the diameter of the heater wire 44 is set to 0.01 mm to 0.2 mm.SELECTED DRAWING: Figure 1

    【課題】融雪機能を発揮しつつ、近赤外線の透過性能の向上を図る。【解決手段】近赤外線センサカバー31は、板状をなし、かつ厚み方向を近赤外線IR1,IR2の送信及び受信の方向に合致させた状態で配置されて、近赤外線IR1,IR2の送信部18及び受信部19を覆うカバー本体部37と、カバー本体部37の厚み方向における後側に配置され、通電により発熱するヒータ線44とを備える。ヒータ線44は、互いに平行に延びる複数の直線部45と、隣り合う直線部45の端部同士を連結する複数の連結部とを備える。隣り合う直線部45の間隔p1は3mm〜10mmに設定され、ヒータ線44の直径は0.01mm〜0.2mmに設定される。【選択図】図1
