An expression is obtained for the coarse-grain entropy of a quantum gas of interacting particles in the low-density approximation. It is shown that in this approximation the coarse-grain entropy obtained satisfies the requirements imposed on the nonequilibrium entropy during the kinetic stage of evolution.
