An exposure apparatus which forms a predetermined mask pattern on a target workpiece through exposure by: casting exposure light upon a mask in which the pattern and a mask-side alignment mark are formed, and forming an image of the mask on the target workpiece by projecting the exposure light, which passes the mask, on the target workpiece through a projection lens, includes: an alignment lighting unit configured to cast, as alignment light, light in a wavelength range included in the exposure light onto the mask-side alignment mark of the mask; and an alignment camera unit including an image pickup device for capturing images, and configured to receive the incident alignment light coming from the alignment lighting unit through the mask and the projection lens. |
