Abstract
The Jeans scale is estimated during the coexistence epoch of quark-glu on and hadron phases in the first-order QCD phase transition. It is sh own that, contrary to previous claims, reduction of the sound speed is so little that the phase transition does not affect evolution of cosm ological density fluctuations appreciably.
