Claim:
1. An exposure apparatus which exposes a substrate by exposure light via a first liquid between an emitting surface of an optical member and the substrate, and that is capable of forming a liquid immersion space on an object movable below the optical member, the exposure apparatus comprising: a first member that is disposed at at least a portion of surrounding of the optical member; a second member that includes at least a portion disposed below the first member, that is capable of being opposite to the object, and that is movable outside an optical path of the exposure light; a protection part that is configured to protect the optical member; a first liquid supply part that is configured to supply the first liquid; and a liquid recovery part that is included in the second member so that the liquid recovery part faces the object, wherein the first liquid supply part is disposed at the first member to face at least one of a space between the first liquid supply part and an outer surface of the optical member and a space including the optical path of the exposure light emitted from the emitting surface, the protection part decreases a change in pressure which the optical member receives from the liquid in the liquid immersion space, and the second member moves so that a relative speed between the second member and the object is decreased during a period of exposure of a plurality of shot regions on the object.
