The problem of the propagation of second sound in superfluid helium is studied. The second sound wave is assumed to be described by a set of variables, the local energy and local energy flux densities. Relaxation function expressions are obtained for the thermal conductivity x which is analogous to the normal thermal conductivity k_T as is distinct from the abnormal thermal conductivity due to the counterflow of the super and normal componenis, and also for the kinetic coefficients ζ_1,ζ_2,ζ_4. It is pointed out that, to the thermal conduc tivity x a restoring force due to temperature is essential.
