  We propose a one-loop neutrino mass model with several $SU(2)_L$ multiplet
fermions and scalar fields in which the inert feature of a scalar to realize
the one-loop neutrino mass can be achieved by the cancellation among Higgs
couplings thanks to non-trivial terms in the Higgs potential and to present it
in a simpler way. Then we discuss our typical cut-off scale by computing
renormalization group equation for $SU(2)_L$ gauge coupling, lepton flavor
violations, muon anomalous magnetic moment, possibility of dark matter
candidate, neutrino mass matrix satisfying the neutrino oscillation data.
Finally, we search for our allowed parameter region to satisfy all the
constraints, and discuss a possibility of detecting new charged particles at
the large hadron collider.
