We calculate the thermal conductivity of electrons and muons produced by Coulomb collisions in neutron star cores taking into account the Landau damping of transverse plasmons in the absence or presence of proton superfluidity. For normal protons, the Landau damping strongly reduces the conductivity, while proton superfluidity suppresses the reduction. The results are described by simple analytic formulae.
