Claim:
1. An exposure apparatus that exposes a substrate, comprising: an optical system that includes an emission surface from which an exposure light is emitted; a first immersion member having a first liquid supply port, an opening through which the exposure light passes, and a first surface that is disposed in a surrounding of the opening, the opening being configured to allow liquid to pass therethrough; a second immersion member having a second liquid supply port and a second surface that is disposed in at least a part of a surrounding of the first surface, the second immersion member being movable relative to the first immersion member; and a first recovery portion that recovers at least a part of liquid in a space between the first immersion member and the second immersion member, the first recovery portion being disposed above a lower end of the space, the liquid in the space including liquid flowed from the lower end of the space, wherein the emission surface, the first surface, and the second surface are opposed to the surface of the substrate in at least a part of the exposure of the substrate, and the substrate is exposed with the exposure light from the emission surface via the liquid between the emission surface and the surface of the substrate.
