Abstract
Provided are a multistage-connected multipole and a charged particle beam device that can be produced with precision in machining without requiring precision in brazing between a pole and an insulation material. This multi-stage connected multipolecomprises: a plurality of poles Q-Qthat are arranged along the optical-axis direction of a charged particle beam, and that have cutouts Non surfaces facing each other; and braces P-Pthat are arranged between the plurality of poles Q-Qand are made of an insulator. The poles Q-Qand the braces P-Pare joined by fitting the braces P-Pinto the cutouts N and applying brazing so as to be interposed by a bonding material.
