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.

Clinical thermometer

Provided are a temperature measuring probe separable from a main body which includes a signal processor, and an electronic clinical thermometer equipped with this probe. The temperature measuring probe includes a temperature measuring circuit supported by a flat, flexible, strip-shaped base member, in which the temperature measuring circuit is sealed by a coating member, such as a film, and/or a filler, one end thereof being treated to form a connector. This structure allows the overall probe to be formed into a film-, sheet- or plate-like configuration. Preferably, a core member is provided between the base member and coating member, with the flexibility and rigidity of the overall probe being decided by selecting the thickness, material and cross-sectional configuration of the core. The temperature measuring circuit preferably is composed of the minimum number of required circuit elements, and individual probes are provided with interchangeability by trimming, selection of characteristics or other treatment.

The core includes at least one cavity. The thickness of the core member at a portion of the at least one cavity being approximately the same as that of the temperature sensing body. The core member has a smoothly diminishing thickness from the at least one cavity toward the rearward end of the probe.
