We calculate the rate of the decay μ→ eγ and the electric dipole moment of the electron in the left-right supersymmetric model when the breaking of parity occurs at a considerably large scale. The low-energy flavor violation in the model originates either from the nonvanishing remnants of the left-right symmetry in the slepton mass matrix or from the direct flavor changing lepton-slepton-neutralino interaction. The result is found to be large for the masses of the supersymmetric particles not far from the electroweak scale and already accessible at the current experimental accuracy. It also provides nontrivial constraints of the lepton mixing in the model.
