<P>PROBLEM TO BE SOLVED: To provide a measuring instrument of thermophysical properties capable of measuring the heat conductivity of a heat insulating material with high precision. Ž<P>SOLUTION: The heat transmitted to a heat flow density detecting means 109 from a heat source 102 through a measuring target 101 during the measurement of thermophysical properties of the measuring target 101 is stored in a heat accumulation material 113 having large specific heat or latent heat in a fixing means 108 to reduce the temperature rise of the heat flow density detecting means 109. As a result, since the temperature rise of a heat flow density sensor 107 can be suppressed, the density of a heat flow passing through the measuring target 101 can be stabilized and the thermophysical properties of the measuring target 101 can be measured with high precision by a simple constitution.
