  We study deformed supersymmetry in N=2 supersymmetric U(N) gauge theory in
non(anti)commutative N=1 superspace. Using the component formalism, we
construct deformed N=(1,1/2) supersymmetry explicitly. Based on the deformed
supersymmetry, we discuss the C-dependence of the correlators. We also study
the C-deformation of the instanton equation for the gauge group U(2).
