The present invention relates to an electromagnetic wave sensor cover which suppresses the reduction of snow melting function and detection function caused by the contact of moisture in the air with a heater part. The cover main body part (23) covers the transmitting part and the receiving part of the near infrared ray sensor from the front of the transmitting direction of the near infrared ray (IR) from the transmitting part. The cover main body part (23) is provided with a base material (24), an undercoat layer (26), a heater part (27) and a SiO2 coating film (31). The base material (24) is formed of a resin material and has near-infrared ray (IR) permeability. The undercoat layer (26) is formed on the rear surface of the substrate (24) in the transmission direction, and has near-infrared ray (IR) permeability. The heater unit (27) is formed in a band shape from copper on the rear surface of the undercoat layer (26) in the transmission direction, generates heat by being energized, and is in close contact with the base material (24) via the undercoat layer (26). The SiO2 coating (31) has near-infrared ray (IR) permeability and covers the heater unit (27).

    本发明涉及电磁波传感器罩,抑制因空气中的水分与加热器部接触而引起的融雪功能以及检测功能的下降。罩主体部(23)将近红外线传感器的发送部以及接收部,从来自该发送部的近红外线(IR)的发送方向的前方覆盖。罩主体部(23)具有基材(24)、底涂层(26)、加热器部(27)以及SiO2覆膜(31)。基材(24)由树脂材料形成,具有近红外线(IR)的透过性。底涂层(26)形成于该发送方向的基材(24)的后表面,具有近红外线(IR)的透过性。加热器部(27)在该发送方向的底涂层(26)的后表面由铜形成为带状,通过通电而发热,并且经由底涂层(26)而与基材(24)紧贴。SiO2覆膜(31)具有近红外线(IR)的透过性,将加热器部(27)覆盖。
