This far-infrared spectroscopy device comprises a holding mechanism that is capable of holding a sample in humid air, a detector for detecting light obtained by emitting far infrared light onto the sample, and a signal processing unit for calculating an absorption spectrum of the sample from a signal from the detector. The signal processing unit comprises a threshold processing unit that subjects the signal from the detector to threshold processing and removes the part of the signal influenced by the absorption by the water vapor in the humid air, a signal interpolation unit that carries out interpolation on the signal that has been subjected to the removal by the threshold processing unit, and an absorbance calculation unit for calculating an absorbance from the signal that has been subjected to the interpolation by the signal interpolation unit.
