Abstract

It is an object to obtain a scanning probe microscope capable of effectively suppressing a reduction in precision in a measurement. A conductive probe (2C) has such a pyramid structure as to be expanded from a tip portion to a bottom surface (a surface on which a cantilever (1) is to be formed) and a semiconductor integrated circuit (12) is formed in a side surface of the conductive probe (2C). An amplifying circuit (12a) to be the semiconductor integrated circuit (12) amplifies an electrical characteristic signal given from the conductive probe (2C) to send the electrical characteristic signal to a signal processor (10) through a conductive cantilever (1C) and a signal cable (9).
