An exposure apparatus in which by filling at least a portion between a projection optical system and a substrate with a liquid and by projecting an image of a pattern onto the substrate via said projection optical system and said liquid, said substrate is exposed, said exposure apparatus includes: a substrate holding member that holds said substrate and keeps liquid so that said substrate is immersed in the liquid; and a liquid supply mechanism that supplies, at a vicinity of the projection area of said projection optical system, liquid onto said substrate from above said substrate.
