The estimation of a portion of energy Eeff/E0 transferred to the EAS elec-tron—photon component at E0 = 10 15 ÷ 1019 eV has been found by using mea-surement data of the Cherenkov radiation and charged particles at the Yakutsk array. The results are compared with the models of different energy dissipation into the EAS electron—photon component and with calculations for different primary nuclei. In the energy intervals of 1015 ÷ 1016 eV and 1018 ÷ 1019 eV Eeff/E0 is equal to (77 ± 2) and (88 ± 2) %, respectively, that doesn’t contradict the mixed composition of primary particles for the first energy interval and the proton composition for the second one. 1.
