摘要： PURPOSE:To inhibit the frequent turning OFF of a power source even though measurement is stopped unless the state when a heat sensitive element is below a specified temperature continues for a specified time, by adopting the two factors, namely the detected temperature of the heat sensitive element and the counted time, as the conditions of the power source OFF. CONSTITUTION:A probe part 1' of one end of a case 1 including a heat sensitive element 2 has a gradually thinning shape, so that the heat sensitive element 2 can be readily inserted into the mouth or the armpit. The other end has a constitution so that a part of it can be separated and attached and a power source battery can be replaced. The heat sensitive element 2 is formed by a thermistor and a cap, which protects the thermistor from mechanical shocks. A sliding type switch 3, which turns ON and OFF the power source, and a display device 4, which displays the liquid crystal numbers as the result of the temperature measurement, are provided in an opening part provided in the case 1. A measured temperature display circuit 5 digitalizes the electric signal corresponding the temperature of the heat sensitive element 2 and makes the display device 4 to display the result. For example, a silver oxide battery is used for a power source microbattery 6, which is enclosed in the rear end part of the case 1.
