ABSTRACT:
A clinical thermometer for measuring the temperature of a living body in a noncontacting manner by receiving infrared radiation from an eardrum or a body surface. An infrared sensor senses infrared radiation incident through an opening portion for narrowing the angle of the field of view of the infrared sensor. An electrical signal from the infrared sensor is converted into the value of the temperature of an object to be measured. A maximum value TP.sub.ob of the converted temperature values is detected. In this manner, the maximum value TP.sub.ob detected when a predetermined time has elapsed from the start of the measurement is determined as the temperature of the object to be measured. The predetermined time at which the measurement is ended is extended in accordance with the time elapsed when the maximum value TP.sub.ob is detected, thereby determining the temperature of the object to be measured.
