An immersion exposure apparatus includes a placement unit on which a substrate is to be placed, the substrate including a body to be processed and a resist film on the body, a projection optical system including a projection lens, a liquid supply unit including an immersion nozzle, a measurement unit for measuring positions of alignment marks Mi (i=1, 2, . . . ) on the substrate, and a control unit for controlling a position of the placement unit on which the substrate is placed so that a pattern image of the photo mask is projected onto a predetermined position on the substrate when immersion exposure to the substrate is performed based on a measurement value acquired by the measurement unit and a correction value for correcting a measurement error resulting from a change of a measurement environment caused during measurement of alignment marks Mi.
