The theoretical analysis of a model of contact which is idealized in one of our test specimen shows that the convergent and divergent heat flows at the metallic contact spots on account of poor thermal conductivity of medium become strong contributory causes for thermal contact resistance. The experimental data on the contact of same metals agree fairly well with the exact solution obtained on the above-mentioned model of contact, assuming that the metallic contact spots are uniformly distributed and their equivalent radii are all of a size and approximately equal to 30μ.
