Claim Text:
1. An analysis apparatus comprising: a column configured to accommodate a secondary electron optical system comprising a charged particle beam source and a lens, the charged particle beam source being configured to generate a charged particle beam and irradiate a sample with the charged particle beam, the lens being configured to control a focal position and a trajectory of the charged particle beam by using an electric field or a magnetic field; at least one detector arranged outside the column and in direct contact with the column, the detector being configured to detect a characteristic X-ray generated from the sample by irradiation of the charged particle beam; and a composition analysis unit configured to analyze a composition of a material constituting the sample from the detected characteristic X-ray, wherein each detector is arranged in such a manner that at least part of its detection surface is placed on the same plane as an exit surface from which the charged particle beam exits from the secondary electron optical system, or placed on the charged particle beam source side away from the same plane.
