  We examine supersymmetric contributions to transition magnetic moments of
Majorana neutrinos. We first give the general formula for it. In concrete
evaluations, informations of neutrino mass matrix elements including CP phases
are necessary. Using unambiguously determined neutrino mass matrices in
recently proposed minimal supersymmetric SO(10) model, the transition magnetic
moments are calculated. The resultant neutrino magnetic moments are found to be
roughly an order of magnitude larger than those calculated in the standard
model extended to incorporate the see-saw mechanism.
