  The ratio of the electron and muon widths of the $J/\psi$ meson has been
measured using direct $J/\psi$ decays in the KEDR experiment at the VEPP-4M
electron-positron collider. The result
$\Gamma_{ee}(J/\psi)/\Gamma_{\mu\mu}(J/\psi)=1.0022\pm0.0044\pm0.0048\
(0.65\%)$ is in good agreement with the lepton universality. The experience
collected during this analysis will be used for a $J/\psi$ lepton width
determination with up to 1% accuracy.
