It is found that when the thermal conductivity of the reference material is known the thermal conductivity of the specimen can be determined theoretically just as in the case of applying the usual hot wire method to a homogeneous material. The error and the reproducibility of the experimental values by this method are within ±4 % and ±1.5 % of the thermal conductivities of standard materials respectively and this method is found very good.
