发明名称 LIQUID IMMERSION MEMBER
摘要 A liquid immersion member is disposed around an optical member having an emergent surface from at least part of which exposure light is emitted and which holds a liquid between itself and an object opposing the emergent surface so that an optical path of exposure light between the emergent surface and the object is filled with a liquid to form an immersion space. The liquid immersion member comprises: an opening that recovers a liquid on the object with a gas; a space into which the liquid and the gas from the opening are entered; a recovery passageway into which only a liquid in the space is entered; an inner side surface that opposes at least part of a side surface of the optical member with a gap therebetween; and a recovery port that recovers at least part of a liquid in the gap.
