Constraints from lepton flavor violating processes are translated into lower bounds on vΔmH±± in the Higgs Triplet Model by considering correlations through the neutrino mass matrix. It is shown that μ → eγ, rare τ decays (especially, τ → μ̄ee), and the muonium conversion can give a more stringent bound on vΔlmH± ± in some parameter regions than the bound from μ → ēee which is expected naively to give the most stringent one. We consider the cases of suppressed μ → ēee not only for CP-conserving sets of phases but also for arbitrary values.
