An image sensor includes a first photoelectric conversion unit that converts light incident through a first opening to an electric charge, a second photoelectric conversion unit that converts light incident through a second opening which is smaller than the first opening to an electric charge, and a signal output wiring that outputs a first signal generated by the electric charge converted by the first photoelectric conversion unit and a second signal generated by the electric charge converted by the second photoelectric conversion unit. The second photoelectric conversion unit is disposed between the second opening and the signal output wiring.

A liquid immersion member is used in a liquid immersion exposure apparatus, and forms a liquid immersion space above an object which is movable below the optical member. The liquid immersion member includes a first member that is disposed at at least a portion of surrounding of the optical member, and a second member that is disposed at at least a portion of surrounding of an optical path of the exposure light and is relatively movable with respect to the first member. The second member includes a second upper surface that is opposite to a first lower surface of the first member via a gap, a second lower surface that is capable of being opposite to the object, and a fluid recovery part that is disposed at at least a portion of surrounding of the second lower surface.
