In gauge models with a bigger number of Higgs particles their couplings to fermions are more complicated than in the standard model. The influence of the Higgs boson exchange on the neutrino production cross section in {ital e}{sup {minus}}{ital e}{sup +} collisions ({ital e}{sup {minus}}{ital e}{sup +}{r_arrow}{nu}{ital N}) is investigated. Our study is done in the framework of the left-right symmetric model with the rich Higgs sector containing a bidoublet and two triplets. The couplings of the Higgs particles even to light leptons can be as large as the gauge boson couplings. The total effect of the Higgs bosons is small as a result of the large Higgs boson mass in the propagators.
