[en] The electroweak corrections at one-loop level to the process H→t bar t are calculated, incorporating the top mass value announced recently by CDF. For M_H<1 TeV where a perturbative calculation is valid, the corrections themselves would gain a few to 20% increment in the decay width as the Higgs-boson mass M_H is increasing within the region, but they are in opposite direction to the QCD ones. If the electroweak and QCD corrections are considered together, the resultant decay width of the mode yields a reduction about a few percent of the tree level one
