In conventional techniques, when a temperature measurement probe that has been corrected is used for the correction of absolute values of temperatures of temperature control blocks of which the temperatures can be controlled individually, there are temperature differences of up to 0.5 DEG C among the temperature control blocks. In the present invention, in contrast, a melting temperature of a temperature correction sample that is housed in each of reaction vessels corresponding to the temperature control blocks is measured as a measurement melting temperature. Subsequently, comparison is made between the measurement melting temperature corresponding to each of the temperature control blocks and a reference melting temperature for the temperature correction sample, and the absolute value of the temperature of each of the temperature control blocks is corrected on the basis of the value of the resultant difference.
