Abstract

To provide a perspiration distribution measurement device or the like, capable of measuring a perspiration state by reducing a load on an object person.SOLUTION: A perspiration distribution measurement device includes a ventilation part (blower 100) for generating airflow toward an object person 99, a detection part (detector 200) for detecting a first temperature distribution on the body surface of the object person 99 when the airflow is generated, and an operation part (operator 300) for calculating and outputting perspiration distribution of the object person 99 based on the detected first temperature distribution.SELECTED DRAWING: Figure 1
