    摘要: An exposure apparatus that exposes a substrate (6) through liquid (18) includes a projection optical system (4) that projects a pattern of an original (2) onto the substrate; a supply port (12) that supplies the liquid; a recovery port (13) that recovers the liquid; and a plurality of pressure resistance portions (22, 24, 25, 27) arranged at a passage of at least one of the supply port and the recovery port, to apply pressure resistances to the liquid passing through the passage. The pressure resistance portions surround a final surface of the projection optical system and are distant from each other in a direction in which the liquid flows through the passage. One of the plurality of pressure resistance portions, which is nearest to the substrate, faces the substrate.
