An image display apparatus is provided with a vacuum chamber consisting of an electron source substrate and an image display substrate, and an ion pump which is attached to an electron-emitting substrate or the image display substrate and exhausts air from the vacuum chamber by the action of a magnet, wherein the magnet is attached and fixed to the substrate to which the ion pump has been attached. Thereby, the image display apparatus prevents the magnet from applying an excessive force to the ion pump by its weight, and acquires a stable structure without causing a vacuum leak.
