The cross section for the process e+e- --> omega pi0 --> pi0 pi0 gamma hasbeen measured in the energy range 1.05--2.00 GeV. The experiment has beenperformed at the e+e- collider VEPP-2000 with the SND detector. The measurede+e- --> omega pi0 cross section above 1.4 GeV is the most accurate to date.Below 1.4 GeV our data are in good agreement with the previous SND and CMD-2measurements. Data on the e+e- --> omega pi0 cross section are well describedby the VMD model with two excited rho-like states. From the measured crosssection we have extracted the gamma^* --> omega pi0 transition form factor. Ithas been found that the VDM model cannot describe simultaneously our data anddata obtained from the omega --> pi0 mu+ mu- decay. We have also tested CVChypothesis comparing our results on the e+e- --> omega pi0 cross section withdata on the tau- --> omega pi- nu_{tau} decay.
