Abstract：
The Fermion mass with aparity violating part in quantum electrodynamics (QED) is allowed in principle and hence introduces a new parameter.Explicit parity violating effect,the electric dipole moment is shown.A chiral rotation may turn the mass into real,however,produces a parity violating term in the pure gauge part.The latter is not the total derivative with respect to time and indeed appears in the equations of motion.The second set of Maxweil equation becomes inhamogineous,which violates parity.
