A folding potential for C-12 + C-12 scattering is constructed based on the alpha-particle model of the nucleus using a free alpha-alpha interaction. This potential gives a good description of the data in the energy region of 70-160 MeV. This report reveals a sort of nuclear system in which the ''elementary particle'' behaves as a free one and thus folding models can be tested more ''cleanly.''
