Claim One:
1. A cross-section processing-and-observation method comprising: a cross-section exposure step of irradiating a sample with a focused ion beam to expose a cross-section of the sample; a cross-sectional image acquisition step of irradiating the cross-section with an electron beam to acquire a cross-sectional image of the cross-section; a step of repeatedly performing the cross-section exposure step and the cross-sectional image acquisition step along a predetermined direction of the sample at a setting interval to acquire a plurality of cross-sectional images of the sample; and a specific observation target detection step of detecting a predetermined specific observation target from the cross-sectional image acquired at the cross-sectional image acquisition step; wherein in the specific observation target detection step, after a predetermined specific observation target is detected, the setting interval of the cross-section exposure step is set to be shorter than that before the specific observation target is detected.
