    Abstract: An immersion exposure system 1 performs an exposure process through a liquid 301 provided between an optical element of a projection optical means 121 and a substrate 111. The immersion exposure system 1 includes a liquid supply section 80 which supplies the liquid 301, an exposure section to which the liquid 301 (301b) supplied from the liquid supply section 80 is continuously introduced along a specific direction and which performs an exposure process in a state in which a space between the optical element of the projection optical means 121 and the substrate 111 is filled with the liquid 301, a liquid recovery section 90 which recovers the liquid 301 (301a) passed through the exposure section 110 at a symmetrical position against the substrate 111, and a liquid recycling section 20 which recycles the liquid 301 (301c) recovered by the liquid recovery section 90.
