PROBLEM TO BE SOLVED: To provide a projection type image display apparatus designed so as to prevent deterioration in performance of an image display element by creating a current of air so that high temperature air may not accumulate around the image display element when cooled. SOLUTION: The rotating shaft of an exhaust fan is disposed so as to be aligned to the direction in which a current of air flows through the image display element. The image display element, a drive circuit substrate (including a power source) and an exhaust fan are arranged in this order from the upstream direction of a current of air flowing from a blowing fan to the exhaust fan to the downstream direction of it.
