Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive polishing condition monitor which can improve monitoring accuracy of the polishing condition. SOLUTION: The surface of a wafer 2 is irradiated with a probe light emitted from a light source via a lens 36. The light reflected on the wafer 2 is incident to an optical system 10 through the lens 36, analyzed by the spectroscopic method by a diffraction grating 42 and received by a linear sensor 43 to measure the spectroscopic characteristic. The amount of the scattered light and diffracted light from the wafer 2 is measured with a photo-sensor 51 of the measuring sections 8, 9. The polishing condition of the wafer 2 is monitored using a measuring signal obtained by the selection depending on the measuring signal obtained from the photo-sensor 51, 51 of the measuring sections 8, 9 among the measuring signals obtained from the linear sensor 43.  As a result, the polishing condition can be monitored based on the spectroscopic characteristic obtained only when a circuit pattern of the particular density is irradiated with the probe light.
