We suggest that this discrete R-symmetry arises from an underlying supersymmetric gauge theory, which gives rise to a scalar inflaton as a composite field. This discrete R-symmetry is common to the dynamical breaking scenarios in global supersymmetry studied several years ago. Some extension of the R-invariance method is also shown.5pages(latex),UT-681High Energy Physics - Phenomenologytext
