Nucleosynthesis in the Universe with isothermal baryon-density fluctuations is investigated. It is shown that neutron diffusion during nucleosynthesis plays an important role. Systematic calculations in the wide ranges of parameters suggest that ΩB=1 is marginally consistent with the light-element abundances (D, 3He, 4He, 7Li) if the Hubble constant is as small as H0=45 km Mpc-1sec-1 or the mean lifetime of neutrons is shorter than 860 sec. Moreover it is found that the abundances of CNO elements in the low-density and neutron-rich region are very small.
