PURPOSE: A thermal conductivity measuring system for high pressure is provided to conveniently and accurately measure the thermal conductivity of an object under high pressure. CONSTITUTION: A thermal conductivity measuring system for high pressure comprises a measuring member(10), an A/D converter, and a controller. The measuring member comprises a receiving member(110), a micro heater(150), and a thermocouple(170). The micro heater is accommodated in the heater receiving part of the receiving member and emits heat to a sample accepted in a receiving space(111). The thermocouple is accepted in the thermocouple receiving part and measures the temperature of heat transferred to both ends from the center of the sample. The A/D converter changes an analog temperature signal output from the thermocouple of the measuring member into the digital signal. The controller controls the micro heater of the measuring member and is embedded with a memory storing an operation equation for computing the thermal conductivity of the sample.
