    J.-M. Kim, S. Bae and I.-S. Lee showed that there exists an isomorphism between the p-primary part of the ideal class group and p-primary part of the unit group modulo cyclotomic unit group in Q (ζpn)+ for all sufficiently large n under some conditions. In the present paper, we shall give an analogue of their result for modular units.
