  We present the full O(alpha) corrections to single Higgs production in e+e-
collision. The computation is performed with the help of GRACE-LOOP where a
generalized non-linear gauge fixing condition is implemented. The numerical
results are checked by testing their UV and IR finiteness as well as their
independence on all five non-linear gauge parameters. We find that for a 500
GeV collider and a light Higgs boson of mass 150GeV, the total correction is
small when the results are expressed in terms of alpha rather than G_mu. For a
higher Higgs boson mass of 350GeV, the correction is of order -10%.
