A cooling system for cooling a semiconductor device including a display device provided in a projection-type image display apparatus with high cooling efficiency without sacrificing cooling performance is disclosed. The cooling system includes a radiating member provided with a convex-shaped heat-receiving portion thermally connected to a heat-generating element mounted on a printed circuit board, and a supporting member provided with an opening penetrating the heat-receiving portion, and a supporting portion for supporting the radiating member. The radiating member is integrally formed of a plurality of radiating fins, a base for supporting and fixing the plurality of radiating fins at one side thereof, and the convex-shaped heat-receiving portion disposed at a bottom face of the base, and the supporting member supports the radiating member from a bottom face of the base.
