An exposure apparatus for exposing a substrate in a vacuum atmosphere includes vibration absorbing mounts that are disposed in a vacuum chamber in order to make it possible to support at least one exposure structure in the vacuum atmosphere with high precision. The at least one exposure structure includes at least one of a mask stage plate, a wafer stage plate, and a barrel surface plate. The vibration absorbing mounts are formed using metallic bellows. By the vibration absorbing mounts, the at least one exposure structure is supported in the vacuum chamber.
