Abstract: There is provided a calorimeter. Heat flows in and out of the sample via a thermoelectric module. The thermoelectric module is so constituted that a pair of a P-type thermoelectric element and an N-type thermoelectric element is disposed between substrates, and the pair of the thermoelectric elements are connected in n pairs so that the P-type thermoelectric elements and the N-type thermoelectric element are arranged alternately in π-shape; a calorimetric sensitivity of the thermoelectric module of a thermal conductance surrounding thermoelectric module and a thermal conductance between substrates of the thermoelectric modules and a noise based on an electric resistance of the thermoelectric module depend on an L/A ratio of the thermoelectric element constituting the thermoelectric module and the number n of the pairs of the thermoelectric elements, where the L/A ratio is 6 mm−1 or more, and the number n of the pairs is 4 or more.
