Summary	The decay η′→ηπ0π0 is studied in the framework of isobar model. It is shown, that good agreement with the experiment is achieved if a0- and σ-meson contributions are taken into account. The contribution of a0-meson is dominant, but σ-meson is necessary to reproduce the form of experimental Dalitz plot. Instead of usual Breit-Wigner form of σ-meson propagator we use parametrization of ππ-amplitude, that satisfies analiticity, crossing, unitarity and chirality constraints. This amplitude has a pole in complex plane, that corresponds to σ-meson and describe experimental data on ππ-scattering in Ke4 decay.
