PROBLEM TO BE SOLVED: To provide a particle size distribution measurement device capable of efficiently draining waste liquid after use in a measurement circulation system and minimizing a preparation time between one measurement and the following measurement for efficiently performing desired measurement in a short time when a plurality of measurement processes are sequentially carried out. SOLUTION: In this particle size distribution measurement device having a measurement circulation system 19 connecting a dispersion bath 2 for dispersing a sample 6 in a dispersion medium 9, a flow cell 16, and a circulation pump 17 via a circulation passage 18, a waste liquid storage tank 22 is connected to the measurement circulation system 19 via a switch valve 20.
