An electronic thermometer utilizes a microprocessor, a bridge circuit containing a temperature responsive transducer, a charge and discharge circuit, and an interrupt signal generating circuit, to provide an accurate temperature measurement while reducing the size of the measuring apparatus. A counted value corresponding to a reference temperature is added to a counted value corresponding to the time it takes a capacitor connected to the bridge circuit to discharge, and the result is converted to a temperature degree displayed after operation in the microprocessor.
