In the framework of the electroweak model with extended Higgs sector including two triplets of the Higgs bosons, besides the standard doublet, and conserving .rho. = 1, widths of Z0 .fwdarw. H0.gamma. decays are calculated, where H0 is one of the four Higgs bosons which appear in this model. The calcns. have been made in the range of parameters .lambda. < 1, m3, m5 .gtoreq. 50 GeV, where .lambda. are coupling consts. in the Higgs potential of the model and m3, m5 are masses of the charged Higgs bosons which appear in this model. For the above mentioned range of parameters we have that the widths of decays can be essentially increased compared to the result of the standard model. In particular, in the range of mass ms .gtorsim. 50 GeV and .lambda. .apprx. 1 the widths of decays can exceed the standard result by two orders.
