The metric perturbations of scalar type in the isotropic Universe filled by a scalar field are considered. The action for such perturbations in terms of gauge invariant variables is obtained and a self-consistent quantum theory is constructed. The inhomogeneities spectrum in the inflationary Universe is calculated.
