  "abstract": "We study the electron thermal transport in granular metals at large tunnel conductance between the grains, $g_T \\gg 1$ and not too low a temperature $T > g_T\\delta$, where $\\delta$ is the mean energy level spacing for a single grain. Taking into account the electron-electron interaction effects we calculate the thermal conductivity and show that the Wiedemann-Franz law is violated for granular metals. We find that interaction effects suppress the thermal conductivity less than the electrical conductivity.",
