An exposure apparatus is provided that performs well a liquid supply operation for forming a liquid immersion region and a liquid recovery operation to form a liquid immersion region in a desired state, thereby allowing high exposure accuracy and high measurement accuracy. The exposure apparatus (EX) exposes a substrate (P) by irradiating exposure light (EL) onto the substrate (P) via a liquid (LQ), and includes a liquid supply mechanism (10) that has a supply port (13) capable of supplying the liquid (LQ) substantially in parallel with a surface of the substrate (P).
