A projector includes an exterior housing of the projector, a first cooling target, and a cooling apparatus provided in the exterior housing and cooling the first cooling target. The cooling apparatus includes a first compressor compressing an operating fluid in a gas phase, a condenser condensing the gas-phase operating fluid compressed by the first compressor into the operating fluid in a liquid phase, a first expander decompressing the liquid-phase operating fluid condensed by the condenser to change to the operating fluid in which the liquid phase and the gas phase are mixed with each other, and a first evaporator changing part of the liquid-phase operating fluid supplied from the first expander to the gas-phase operating fluid by using heat transferred from the first cooling target and discharging the gas-phase operating fluid to the first compressor.
