An exposure apparatus for projecting a pattern of an original onto a substrate using exposure light includes a projection optical system to project the pattern onto the substrate; a shielding structure, having an opening through which the exposure light passes, to shield the projection optical system from an outside environment; and an attraction system, including at least one of a panel to generate an electric field and a cryogenic panel arranged to face a path of the exposure light passing through the opening, to attract contaminants.
