An aberration corrector includes: a first multipole and a second multipole configured to form a hexapole field; and a transfer optics including a plurality of round lenses. The transfer optics is disposed between the first multipole and the second multipole, and acts on a charged particle beam such that an absolute value of a slope of the charged particle beam passing through the first multipole is different from an absolute value of a slope of the charged particle beam passing through the second multipole.
