We have considered the metal enrichment of the intergalactic medium (IGM) and Lyα clouds at high redshifts. The CIV absorption lines associated with the Lyα forest have been observed (e.g. Songaila & Cowie 1996) and the metallicity is estimated as ~0.01Z⊙. Here, based on a galactic wind model, we have examined how the IGM is metal-enriched by the outflows driven by supernova explosions in primeval galaxies and minihalos.
