  A search for the decay Ks->pi0e+e- has been made by the NA48/1 experiment at
the CERN SPS accelerator. Using data collected during 89 days in 2002 with a
high-intensity Ks beam, 7 events were found with a background of 0.15 events.
The branching fraction BR(Ks->pi0e+e-, m(ee) > 0.165 GeV/c^2) =
(3.0^{+1.5}_{-1.2}(stat) +/-0.2 (syst)) x 10^{-9} has been measured. Using a
vector matrix element and a form factor equal to one, the measurement gives
BR(Ks->pi0e+e-) = (5.8^{+2.9}_{-2.4}) x 10^{-9}.
