摘要：

The measurement of the tHrmal diffusivity of a fine wire is developed, using a light-irradiation-type ac calorimetric method. It is pointed out that in the analysis, the contribution of heat loss or external relaxation time should be taken into account for the measurement of a fine wire. To examine the measurement, a wire of stainless steel with a diameter of 30-mu-m is used as a sample and the test is carried out in the wide frequency range of 1-25 Hz. The result obtained agrees with the v alue reported for the bulk material.
