Based on a position measurement value measured by the first measurement unit and position measurement values measured at different timings by the second measurement unit, the control unit controls the position of the beam irradiated to the substrate. The position measurement values measured at the different timings are values obtained from the same mark or values obtained from two marks adjacent to a common shot area.
