摘要： A projector includes an exterior housing including an exhaust port and a cooling device provided in the exterior housing and configured to discharge the air, which has cooled a cooling target, to the outside of the exterior housing via the exhaust port. The exterior housing includes a partition member that partitions the exhaust port and forms a plurality of openings. The partition member includes projecting sections projecting from an end edge of at least one of the plurality of openings into the opening.
