    Abstract: PROBLEM TO BE SOLVED: To provide a charged particle beam column not generating image shift or deterioration of image resolution when slanting the beams in large angles.
    SOLUTION: On the charged particle beam column comprising an aberration correction device 10, a convergent charged particle beam is formed, slanted against a sample 18 face in large angles by controlling an incident direction of the beams incident on a second condenser lens 7 without moving an object point of the condenser lens by using a deflection device 51, and also without moving an object point of an objective lens 17 located on a beam axis. At this time, the image shift or deterioration of image resolution due to the slanting of the beams is prevented by the aberration correction device 10.
