Abstract: An infrared sensor cover is configured to cover an emitter and a receiver of an infrared sensor from the front with respect to an emission direction of infrared rays. The infrared sensor cover includes a cover body that allows passage of infrared rays. The cover body includes an anti-reflection layer that restricts reflection of emitted infrared rays. The anti-reflection layer serves as at least one of two opposite surfaces of the cover body in the emission direction. The anti-reflection layer has a uniform thickness. The anti-reflection layer is configured so that transmittance of the infrared rays through the cover body is maximal when the infrared rays are emitted onto the anti-reflection layer at an incident angle within an angular range of 30 degrees to 60 degrees, inclusive.
