PROBLEM TO BE SOLVED: To provide a projector capable of enhancing a hot air discharging efficiency, capable of increasing the discharging speed, and also, capable of suppressing a noise due to irregularities in the hot air current. SOLUTION: In the projector including a housing, a fan, a radiating pipe and a rectifier blade, an inside opening end and an outside opening end are formed in the radiating pipe, the outside opening end is formed on the housing, besides, the rectifier blade is formed inside the radiating pipe, then, the hot air flowing inside the radiating pipe is guided and the speed of discharging the hot air from the radiating pipe is increased.
