PROBLEM TO BE SOLVED: To provide a particle size distribution measuring device by which a numerical table demonstrating the relation of particle diameters to particle amount can be observed intuitively without misreading a numerical value. SOLUTION: The particle size distribution measuring device 1 includes: a calculation unit 82 for measuring the intensity distribution of diffraction and scattered light by irradiating a measuring object with laser light and calculating the particle size distribution of a particle group to be measured included in the measuring object from the measured results of the intensity distribution; and a display control unit 83 for displaying the particle size distribution of the particle group to be measured calculated in the calculating unit 82 as the numerical table which demonstrates the relation of the particle sizes to the particle amount, wherein the display control unit 83 displays in such a way that the part corresponding to the set information in the numerical table is pointed based on the set information indicating the specific particle size or the specific particle amount set by an input device 72.
