  Within the model based on the $SU (2)_L\times SU (2)_R\times U (1)_{B-L} $
gauge group and having the bidoublet and two triplets of the Higgs fields
(left-right model) the Higgs sector impact on the value of the muon anomalous
magnetic moment is considered. The contributions coming from the doubly charged
Higgs bosons, the singly charged Higgs bosons and the lightest neutral Higgs
boson are taken into account. The obtained value of the muon anomalous magnetic
moment is the function of the Higgs boson masses and the Higgs boson couplings
constants (CC's). We express the most of part of the CC's as the functions of
the heavy neutrino sector parameters. We show that at the particular parameters
values the model under study could explain the BNL'00 result.
