Near-infrared sensor cover

A near-infrared sensor cover configured to cover a transmitting unit and a receiving unit for near-infrared rays in a near-infrared sensor, the near-infrared sensor cover comprising:

• a cover body having transmissiveness to near-infrared rays, wherein
• the cover body includes:
• a base made of a plastic, and
• a heater unit that 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 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, and
• the asperities include a reflection suppression surface that is inclined relative to the transmission direction and reduces reflection of the near-infrared rays.
