According to the invention, there is provided a projector having a light source unit 63, a light source side optical system which includes a color wheel and a light guiding unit, a display device, a projection side optical system and a cooling fan and comprising a projector control unit, wherein an interior of a projector casing is divided into an outlet side spatial compartment 122 which is positioned on an outlet side of the cooling fan and in which the light source unit 63 is disposed and an inlet side spatial compartment which is positioned on an inlet side of the cooling fan. In addition, this outlet side spatial compartment 122 is covered thereabove by an upper division board 125 above which a heat conductive sheet 128 which is formed of an aluminum sheet is disposed. Further, this heat conductive sheet 128 is electrically connected to the projector casing, so that electricity charged in the heat conductive sheet 128 can be discharged.
