    Abstract: Disclosed is an exposure apparatus which includes an optical element (1), a gas supplying unit (4) for supplying a predetermined gas around the optical element (1), and an organic compound decomposition mechanism (7,8) for decomposing an organic compound in the gas. This structure prevents adhesion of organic compounds to the optical element (1) without a necessity of using many filters in combination.
