PROBLEM TO BE SOLVED: To measure a value related to the dissipation or a value that is proportional to dissipation energy, without basing on the premise of steady state. SOLUTION: This microscope is equipped with an excitation means 12 for exciting, following a resonance frequency of a cantilever 2; a displacement detector 10 for detecting the displacement of a probe on the tip of the cantilever 2; an amplitude detector 20 for successively acquiring the amplitude from a signal from the displacement detector 10; a difference value detector 21 for acquiring the time difference value of the amplitude; a divider 22 for acquiring a quotient value between each time differential value; a logarithmic converter 23 for acquiring a logarithmic value of the quotient value; and a second divider 24 for acquiring the value, relative to dissipation by acquiring a value determined, by dividing the logarithmic value by a differential time.
