<p>PROBLEM TO BE SOLVED: To provide a heat conductivity measuring apparatus capable of measuring heat conductivity at high to low temperatures under environments such as in air, vacuum and gas atmospheres easily and in a short time, and a heat conductivity measuring method.SOLUTION: The heat conductivity measuring apparatus comprises: an infrared heating source using a lamp or a laser as a light source, and disposed on a heated surface side of a flat plate-like sample; a temperature sensor measuring temperatures of front and back surfaces of the flat plate-like sample; and a heat flux sensor disposed on a non-heated surface side of the flat plate-like sample. The measuring apparatus heats one surface of the flat plate-like sample by infrared, and measures heat conductivity from the front and back surface temperatures of the flat plate-like sample and a heat flux value measured on the non-heated surface side.</p> |
