ABSTRACT:
Disclosed is a thermometer using a thermo-sensitive element such as a thermistor, in which in the beginning of temperature measurement energization of the thermo-sensitive element is effected for self-heating thereof so that the temperature of the thermo-sensitive element is raised by the self-heating near the temperature to be measured faster than in case of the heat only received from the object to be measured, and thereafter the cessation of energization makes the temperature of said thermo-sensitive element follow the temperature of the object to be measured and finally equal to the same, resulting in carrying out the measurement in a short time.
