A scanning exposure apparatus which transfers a pattern of a mask within an illumination area formed in a predetermined shape onto a substrate by illuminating said illumination area formed in said predetermined shape with a predetermined energy beam, the apparatus comprising: a mask stage which holds said mask; a substrate stage which holds said substrate; and a controller, connected to said mask stage and said substrate stage, which provides relative movement between a plurality of measuring marks provided on said mask and a reference mark provided, in correspondence with a part of said measuring marks, on said stage, to obtain information with respect to positions of said measuring marks and said reference mark, and which obtains a hypothetical coordinate system on said mask based on a coordinate system on said mask and said information with respect to said positions, and which obtains a writing error of said measuring marks based on said hypothetical coordinate system.
