There is provided a scanning probe microscope capable of simply and accurately confirming whether or not a sample shape satisfies specified conditions. A pseudo reference image Sref1 comprises a pair of reference line profiles Lref1 and Lref2 arranged apart form each other in parallel. An operator moves and rotates the position of the pseudo reference image Sref1 on a screen so that a sample shape line profile fits between the reference line profiles Lref1 and Lref2 of the pseudo reference image Sref1. If it is possible to fit the line profile of the sample shape between the reference line profiles Lref1 and Lref2, it is determined that the sample shape is in spec, while if it is not possible to fit the line profile of the sample shape between the reference line profiles Lref1 and Lref2, no matter how the pseudo reference image Sref1 is moved and rotated, it is determined that the sample shape is out of spec.
A scanning probe microscope for causing a probe provided on a free end of a cantilever to approach or contact a sample surface, scanning in X and Y directions while moving slowly in a Z direction so that a distance between the probe and the sample surface is kept constant, and displaying a sample image based on a strain amount of the cantilever, comprising:
