  One loop correction to the SUSY Ward-Takahashi identity is calculated on
lattice with Wilson fermion. The supersymmetry on lattice is broken explicitly
by the gluino mass and the lattice artifact. We should fine tune parameters in
the theory to the point given by the additive mass correction in order to
eliminate the breaking effect of lattice artifact. It is shown that the
additive mass correction appearing from the SUSY Ward-Takahashi identity
coincide with that from the axial $U(1)_R$ symmetry as was suggested by Curci
and Veneziano. Two important symmetries of the super Yang-Mills theory can be
recovered simultaneously in the continuum with a single fine tuning.
  Operator mixing of the supercurrent are also investigated. We find that the
supercurrent mixes only with a gauge invariant current $T_\mu$ which is related
to the gamma-trace anomaly.
