Abstract
There is provided a near-infrared sensor cover to be applied to a near-infrared sensor including a transmitting unit that transmits near-infrared radiation to outside of a vehicle and a receiving unit that receives near-infrared radiation reaching and reflected by an object outside the vehicle, and to cover the transmitting unit and the receiving unit. The near-infrared sensor cover includes a luster layer formed by dispersing a filler in a coating film, the filler including a core and a shell that covers the core with a material having a refractive index different from that of the core. Light transmittance of near-infrared radiation in the near-infrared sensor cover is 60% or more.
