The projection type image display apparatus is equipped with a lamp unit (22), an optical block (21) which modulates light from the lamp unit and projects an image signal, a circuit board (24) having via holes and on which an external connector (25) is mounted, and a cabinet (2) for housing the aforementioned elements. The display apparatus is equipped with a back cover (26) provided to cover around the external connector from the outside and a dustproof cover (29) provided to cover around the external connector from the inside. A closed space is formed by the circuit board, the back cover (26) and the dustproof cover (29), and the dustproof cover closely shields at least a space below the circuit board from the exterior. Excellent dustproof characteristics enabling use even in installation environments with a large amount of dust and dirt can be obtained.
