PROBLEM TO BE SOLVED: To provide an exposure adjustment method capable of simply compensating a change in a position, a shape, and a focal position of an image on a wafer. SOLUTION: The charged particle beam exposure apparatus adopts the split exposure transfer system for using charged particle beams to expose and transfer a pattern formed on a reticle onto a sensitive substrate such as a wafer; stores a correction amount applied to a projection optical system to compensate the change in the position, shape, and focal position of the image on the wafer caused by a flection of the reticle, in an optical axis direction of an exposed position in a form of a table as data unique to each position on the face of the reticle; and adjusts the projection optical system at exposing and transferring depending on the exposed position of the reticle on the basis of the corresponding correction amount in the table.
