We calculate the amplitude of density fluctuations generated during de Sitter phase of the inflationary universe without introducing the concept of the classical scalar field. This is done by directly evaluating the quantum two-point function of a certain combination of the components of the scalar field energy-momentum tensor which is invariant under coordinate gauge transformations. We find the amplitude agrees with that obtained in literature in which the existence of the homogeneous classical field is assumed, provided that the de Sitter-invariant quantum state of the field is manifestly unstable.
