PROBLEM TO BE SOLVED: To obtain a measuring method in which specific heat in a high-temperature region can be measured with high accuracy in the small number of measuring operations even when a temperature around a sample is not uniform. ;SOLUTION: A heat flux-type differential scanning calorimeter has a structure wherein a second heat flowmeter plate 2 on which two empty cells are arranged in a position No. 3 and a position No. 4 which are symmetric with a sample and a standard sample is installed at the lower part of a first heat flowmeter plate 1 on which the sample and the standard sample are arranged in a position No. 1 and a position No. 2, and the end part of the first heat flowmeter plate 1 and the end part of the second heat flowmeter plate 2 are brought thermally into contact with a soaking container 7 in a state thet the end parts are brought into contact with each other. In a process in which the soaking container 7 is heated at a set temperature change speed, the temperature difference between the sample arranged on the first heat flowmeter plate 1 and a reference sample arranged on the second heat flowmeter plate 2 and the temperature difference between the standard sample arranged on the first hear flowmeter plate 1 and the reference sample arranged on the second heat flowmeter plate 2 are measured simultaneously by using the heat flux-type differential scanning calorimeter. The value of the specific heat of the sample is found on the basis of their measured values and on the basis of the known specific heat value of the standard sample.;COPYRIGHT: (C)1999,JPO
