PROBLEM TO BE SOLVED: To provide a fatigue degree evaluation system capable of efficiently presenting fatigue degree to a subject.SOLUTION: A fatigue degree evaluation system 1 comprises a calculation part 2. The calculation part 2 designates one first mark corresponding to a first measurement result which indicates objective fatigue degree of a subject out of a first mark group which indicates objective fatigue degree in a step-by-step manner. The calculation part 2 designates one second mark corresponding to a second measurement result which indicates subjective fatigue degree of the subject out of a second mark group which indicates subjective fatigue degree in a step-by-step manner. In addition, the calculation part 2 creates image data of a fatigue degree evaluation image based on the first and second measurement results of the subject. The fatigue degree evaluation image includes a first image in which the first and second marks are arranged in a fatigue degree evaluation region. Arrangement positions of the first and second marks are changed in the fatigue degree evaluation region, according to the first and second measurement results of the subject.SELECTED DRAWING: Figure 1
