Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a projector improving cooling efficiency by using a cooling liquid and securing safety against leakage of the cooling liquid. SOLUTION: A cooling unit 50 is disposed in an area spatially partitioned at least from an optical unit 20 and an electric circuit unit 40. The installation position of piping 53 between the cooling unit 50 and cooling members (power supply parts 21, 24, 27) and the installation position of wiring 70 from the electric circuit unit 40 are separated from each other.
