Abstract: The cross section for the $e^+e^- \to \omega \pi^0 \to \pi^0\pi^0\gamma$ process has been measured in the energy range of $1.1$–$1.9$ GeV. The measurement has been made with the Spherical Neutral Detector at the VEPP-2000 $e^+e^-$ collider. The data in the energy range of $1.1$–$1.4$ GeV are in agreement with the earlier measurements with the SND and CMD-2 detectors. The cross section has also been measured above $1.4$ GeV.
