PROBLEM TO BE SOLVED: To realize a fluorescence spectrophotometer in which a fluorescence intensity peak can be extracted with satisfactory efficiency from three- dimensional measured data. SOLUTION: In the fluorescence-peak detecting method in which a fluorescence peak is detected based on three-dimensional setting data on an excitation- light-side wavelength, a fluorescence-side wavelength and a fluorescence intensity obtained as a result by measuring a sample, a peak candidate point obtained by performing the wavelength scanning operation of excitation data in the three-dimensional measured data is compared with a peak candidate point obtained by performing the wavelength scanning operation of fluorescence, and a peak candidate point which is common to both is selected as a three- dimensional peak candidate point. Whether the three-dimensional candidate point is a peak obtained by the fluorescence or not is judged. Thereby, in a fluorophotometer which handles three-dimensional data, a fluorescence peak which appears in a part very close to scattered light and even a peak whose shape is hard to distinguish can be recognized with satisfactory accuracy.
