Recent observational studies show considerable small dispersions for abundance ratios of C-Zn relative to iron in metal-poor halo stars. On the other hand, abundance ratios of neutron-capture elements show large scatters, suggesting incomplete mixing of the interstellar medium at the beginning of the Galaxy. We attempt to explain these contradictory observations, using an inhomogeneous chemical evolution model, which is shown to well reproduce large scatters in neutron-capture elements in our previous studies. In particular, taking into account of difference of observational trends among iron-peak elements, we discuss nucleosynthesis of the very first stars.
