Abstract: A sensor unit to be mounted on a vehicle, the sensor unit includes: a LiDAR; a housing configured to accommodate the LiDAR; and a cleaner attached to the housing and including a first nozzle configured to jet air at a first surface to be cleaned corresponding to the LiDAR and a second nozzle configured to jet a cleaning liquid at the first surface to be cleaned. The first nozzle is disposed above the second nozzle, a jetting direction of the air from the first nozzle is a direction that is parallel to a horizontal direction or a direction that is more downward-trending than the horizontal direction, and a jetting direction of the cleaning liquid from the second nozzle is a direction that is more upward-trending than the horizontal direction.
