  The full electroweak radiative correction is calculated for the process ee-->
nunubarHH which is a window for the study of the Higgs potential at the future
linear collider. The calculation is done by using GRACE, the automated system
for the calculation of Feynman diagrams. The magnitude of the weak correction
in the G-mu scheme is small in the high energy region where this process
dominates over the ZHH production.
