A near-infrared sensor cover includes a cover body having transmissiveness to near-infrared rays. The cover body includes a base and a heater unit. The heater unit is arranged rearward of the base in a transmission direction of the near-infrared rays and includes a wire-like heating element. The heating element is configured to generate heat when energized. The base includes a rear portion that includes a rear surface of the base in the transmission direction. In the rear portion of the base, at least part of a section that is different from a section in which the heater unit is provided is formed by a reflection suppression structure including asperities. The asperities include a reflection suppression surface that is inclined relative to the transmission direction and reduces reflection of the near-infrared rays.
