A projector includes a first cooling target and a cooling device. The cooling device includes a first compressor configured to compress working fluid in a gas phase, a condenser configured to condense the working fluid in the gas phase into the working fluid in a liquid phase, a first expander configured to decompress the working fluid in the liquid phase, a first evaporator configured to change the working fluid flowed from the first expander to the working fluid in the gas phase with heat of a first cooling target and discharge the changed gas-phase working fluid to the first compressor, a first pipe connecting the first compressor and the condenser, a second pipe connecting the condenser and the first expander, and a base to which the first compressor, the condenser, and the first expander are fixed. The first pipe and the second pipe are provided in the base.
