Abstract

Conventional devices have been difficult to use due to insufficient consideration being given to factors such as the cost necessary for diaphragm replacement and the convenience of the work. In the present invention, a diaphragm mounting member installed in a charged particle beam device for radiating a primary charged particle beam through a diaphragm separating a vacuum space and an atmospheric pressure space onto a sample placed in the atmospheric pressure space is provided with a diaphragm installation portion to which a TEM membrane is mounted and a casing fixing portion mounted on a casing of the charged particle beam device. The diaphragm installation portion has a positioning structure for positioning a platform on which the diaphragm is held.
