Abstract: A specific representation of the known one-loop EW correction to the relation between the pole and running $\overline{\text{MS}}$-cheme masses of the top-quark through particle masses of the Standard Model is given within the Fleischer–Jegerlehner tadpole scheme, where the vacuum expectation value of the Higgs field is renormalized. The importance of taking into account both the EW and QCD effects in this relation in the considered case is emphasized. It is noted that the discard of the EW corrections leads to over 10 GeV shift in the difference between the pole and running t-quark masses. This magnitude exceeds essentially the modern uncertainties of the considered relation, following from the treatment of the Tevatron and LHC data where both pole and running $t$-quark masses are defined in the widespread approach when only the QCD corrections are kept in mind between them.
