PROBLEM TO BE SOLVED: To provide a living body risk evaluation device capable of evaluating an onset risk of a heat illness or dehydration in a living body in advance.SOLUTION: A living body risk evaluation device 1 comprises: a temperature sense measurement part 11 a perspiration degree measurement part 16 and an evaluation part 20. The temperature sense measurement part 11 measures a temperature sense of a living body, and comprises: a heat application part 12 for applying warmth or cold to a prescribed portion of the living body a temperature detection part 13 for detecting temperature of the prescribed portion of the living body or the temperature of the vicinity thereof and a sensation operation detection part 14 for detecting a sensation operation which indicates that the living body sensed temperature change. The perspiration degree measurement part 16 measures a perspiration degree of moisture from a living body surface, and comprises: a covering part 17 for covering a part of the living body in an almost sealing state and a moisture content detection part 18 for detecting a moisture content in a space covered with the covering part 17. The evaluation part 20 evaluates an onset risk of a heat illness or dehydration based on the temperature sense of the living body or the perspiration degree of moisture from the living body surface.SELECTED DRAWING: Figure 1
