  We study sphaleron solutions in the next-to-minimal supersymmetric standard
model. We find that the boundary condition on the singlet field at the origin
of the radial coordinate is of Neumann type, while the other boundary
conditions are of Dirichlet type. The sphaleron energy takes almost the same
value as in the MSSM for wide range of parameters, in spite of the negative
contribution from the cubic term in the Higgs potential.
