The time of the energy relaxation of electrons due to electron-phonon interaction in the films of a high-temperature superconductor YBaCuO has been measured for the first time. The results show that the electron-phonon interaction strength in this compound increases considerably in comparison with that of the ordinary superconducting metals.
