Beschreibung
Zusammenfassung:	Provided is a charged particle beam device which includes a storage unit that stores relationship information indicating a relationship between intensity or an intensity ratio of a charged particle signal obtained when a layer disposed on the sample is irradiated with the charged particle beam and a thickness of the layer; and a calculation unit that calculates the thickness of the layer as a thickness of the sample by using the relationship information and the intensity or the intensity ratio of the charged particle signal.
