Abstract

A particle size distribution measuring device includes an actual spectrum obtaining unit obtaining an actual spectrum which is a light intensity spectrum; a non-target spectrum calculating unit that receives non-target particle size distribution data indicating a particle size distribution of a non-target particle group which is not a measurement target and which is accommodated in the cell and that calculates, on the basis of the non-target particle size distribution data, a non-target spectrum which is a light intensity spectrum to be obtained by irradiating the non-target particle group with light; a non-target spectrum removing unit that calculates a target spectrum which is a light intensity spectrum obtained by subtracting an influence of the non-target spectrum from the actual spectrum; and a target particle size distribution calculating unit that calculates the particle size distribution of the particle group which is the measurement target on the basis of the target spectrum.
