The first evidence of the decay B0 → ρ 0π0 is discussed. The data collected at the υ(4S) resonance with the Belle detector at the KEKB asymmetric e+e - collider is used for the purpose. 15.1±4.8 signal events are detected with a significance of 3.5 standard deviations. The branching fraction is also measured which equals to (5.1 ± 1.6(stat) ± 0.9(syst)) × 10 -6.
