Abstract

The object of the invention is to provide a thermal conductivity measuring device that comprises a heat generator arranged in such a way as to come into contact with an object to be measured for thermal conductivity, a heat resistant material arranged in such a way as to come into contact with the heat generator, at least one pair of differential thermocouples for measuring a voltage value caused by the difference in temperature of two points of the heat resistant material, the temperature being generated by allowing heat to flow from the heat generator, and a calculating device for calculating the time rate of change of output voltage of the differential thermocouples and then calculating the thermal conductivity of the object to be measured on the basis of the calculated time rate of change.
