A vehicle sensor unit includes an infrared sensor configured to transmit an infrared ray to an outside of the vehicle, and receive an infrared ray reflected by a detection target object outside the vehicle, and a cover which is located in front of the infrared sensor in a transmission direction of the infrared ray to cover the infrared sensor and through which the infrared ray passes. A plurality of fine projection portions are formed on a surface of the cover on an opposite side of a surface on an infrared sensor side, at least in a region through which the infrared ray passes, and an interval between the projection portions that are adjacent to each other is equal to or smaller than a wavelength of the infrared ray.
