PURPOSE: To provide a spectrum analyser capable of simply obtaining a component contained in a sample even when the size or shape of the sample is different.
CONSTITUTION: The spectrum analyser is equipped with an irradiation part 3 irradiating a sample with the measuring luminous flux from a light source 1, a light detection part 4 detecting the light passing through the sample and a spectrum analyzing means 6 obtaining the spectrum of the transmitted light detected by the light detection part 4 to obtain the component contained in the sample on the basis of the obtained spectrum. Further, an interval altering means 7 altering the interval between the irradiation part 3 and the light detection part 4 and an interval measuring means 8 measuring the interval between the irradiation part 3 and the light detection part 4 are provided and the spectrum analyzing means 6 corrects the component calculated on the basis of the interval measured by the interval measuring means 8.
