PROBLEM TO BE SOLVED: To provide an inexpensive soot concentration measuring device simplified in measurement. SOLUTION: This device is equipped with a light source 2 for making measuring light I incident to sample gas G, a photodetector 3 for detecting the intensity of scattered light generated in the sample gas G, and a computing unit 4 for operating a soot concentration in the sample gas G by substituting the scattered light intensity detected by the photodetector 3 for a concentration proportional formula for determining a soot dimension from the scattered light intensity.
