We study the spin-Peierls states in the presence of spin defects for CuGeO<SUB>3</SUB> where magnetic ions Cu<SUP>2+</SUP> are replaced by non-magnetic ones Zn<SUP>2+</SUP>. Based on the action for the bosonized Hamiltonian, we investigate the spatial dependence of the phase which expresses the spin fluctuation. Further, we calculate temperature dependence of the magnetic susceptibility by taking account of the spatial variation of the phase.
