PROBLEM TO BE SOLVED: To increase the number of openings which can be selected without changing a size of a region of the opening which can be selected in electron optics and reducing an effective drawing speed, and enhance throughput. SOLUTION: In a successive transfer electron beams drawing method, after a specific region stripe 17A is drawn, movement is performed from an opening A to an opening B for a return time (a) of a stage. Thereafter, drawing of a strip 17B is started. At this time, a position of the opening is measured and a stop error quantity of the opening is made feedback to a beam biasing position on a sample, whereby correction is made and high precise drawing is performed. Incidentally, at the time of return of a stage from the stripe 17A to 17B as described above, movement of the opening is made, and additionally at the time of return of the stage from a chip 16 to a next chip, the movement of the opening may be made.
