Using 3.3 pb−1 of data collected with the CMD-2 detector in the 720 -- 840 MeV c.m. energy range, the branching fraction of the conversion decay ω→π0e+e− has been measured: B(ω→π0e+e−)=(8.19±0.71±0.62)⋅10−4. The upper limits for the branching fractions of the following conversion decays have been obtained at the 90% confidence level: B(ρ→π0e+e−)<1.6⋅10−5, B(ρ→ηe+e−)<0.7⋅10−5 and B(ω→ηe+e−)<1.1⋅10−5.
