We examine the supersymmetric non-linear O(N) sigma model with a soft
breaking term. In two dimensions, we found that the mass difference between
supersymmetric partner fields vanishes accidentally. In three dimensions, the
mass difference is observed but O(N) symmetry is always broken also in the
strong coupling region.
