PROBLEM TO BE SOLVED: To provide a projector enhancing dust resistance of a cooling object and allowing a cooling fan to be easily replaced with a new one.SOLUTION: A projector comprises: a circulation cooling device 5; a control section 10 being disposed outside the circulation cooling device 5 and controlling the projector; and an exterior housing accommodating the circulation cooling device 5 and the control section 10 and constituting an exterior. The circulation cooling device 5 comprises: a cooling fan 53 being disposed in a sealed housing and blowing cooling gas to a cooling object; a heat absorption section 55 absorbing heat of the gas cooling the cooling object; and a relay section 8 forming a sealed space together with the sealed housing and relaying electrical connection between the cooling fan 53 and the control section 10. The relay section 8 comprises a double-sided board having a connection member electrically connected to the cooling fan 53 on an inner surface being a sealed space side and a connection member electrically connected to the control section 10 on an outer surface being an opposite side to the sealed space side.SELECTED DRAWING: Figure 3 |
