摘要： A projector includes a cooling device configured to cool an electrooptical device serving as a cooling target. The cooling device includes a closed housing in which the electrooptical device is disposed and a circulation channel for circulating cooling air is formed, a circulation fan configured to circulate the cooling air in the closed housing, and a heat absorber disposed on the circulation channel and configured to absorb heat of the cooling air in the closed housing. The closed housing includes, on the inner side, an inner wall section that forms the circulation channel having an annular shape. The heat absorber is disposed on the opposite side of the electrooptical device across the inner wall section.
