Abstract
In an electronic apparatus, a contact thermometer contacts a skin surface of a user and measures a first temperature of the skin surface. A radiation thermometer measures a second temperature of the skin surface of the user. A vaporization heat quantity calculating unit calculates a quantity of heat of vaporization, using the first temperature and the second temperature. The calculation of the quantity of heat of vaporization is performed by executing predetermined vaporization heat quantity computing processing in which the first temperature and the second temperature are variables.
