description An exposure apparatus exposes a substrate with an exposure light via a projection optical system and a liquid, and includes a flow channel forming member and a substrate stage. The flow channel forming member forms an immersion area of the liquid at an image surface side of the projection optical system. The substrate stage has a wall portion provided so as to surround a support portion which supports the substrate, and a recovery port capable of recovering the liquid in a recess formed at an outside of the wall portion with respect to an optical axis of the projection optical system. When a cleaning is performed, a cleaning liquid is recovered via the recovery port.
