Beschreibung
Zusammenfassung:	The present invention aims at providing an ion milling device that can set a high-precision processing area with a simple structure. In order to achieve the above object, there is proposed an ion milling device including a sample holder that holds a sample and a mask partially restricting irradiation of the sample with an ion beam, in which the sample holder includes a first contact surface that contacts with an end surface of the sample located on a passing orbit side of the ion beam, and a second contact surface that contacts with an end surface of the mask so that the mask is located at a position spaced apart from the ion beam more than the first contact surface.
