Abstract
A beam arrangement portion is provided to arrange multiple primary electron beams on a substrate. The beam arrangement portion arranges the multiple primary electron beams in a square lattice along a first moving direction of a stage allowing the substrate to be placed thereon and a second moving direction perpendicular to the first moving direction in a state where, when the multiple primary electron beams are viewed as a whole, beams around four corners of the square lattice are omitted.
