PROBLEM TO BE SOLVED: To accurately detect a heat flow generated between a living body surface and an outside environment.SOLUTION: A heat flow sensor 30a is equipped with a first protection layer 32 brought into contact with a skin surface of a user; a second protection layer 33 facing an outside environment; and a detector 40a which is disposed between the first protection layer 32 and the second protection layer 33, and detects a heat flow generated between the skin surface and the outside environment. In the herat flow sensor 30a, the second protection layer 33 is formed by material whose emissivity satisfies the same degree condition as the emissivity of a human skin.SELECTED DRAWING: Figure 3 |
