PROBLEM TO BE SOLVED: To provide an observing method and a scanning probe microscope capable of observing the electric characteristic state of an electric carrier such as mobility in an organic membrane, etc., with high resolution. SOLUTION: An object of observation 3 is irradiated with light 4, and a voltage is impressed on the object of observation 3 with a probe 11 having a sharp tip brought in contact with or close to the object of observation 3. Positive holes and electrons are isolated from excited molecules generated in the object of observation 3 by the absorption of the light, and charge obtained by this is extracted from the object of observation 3 and detected.
