The Hadamard regularization calculation in carried out to obtain the renormalized stress tensor of scalar fields with respect to the de Sitter invariant vacuum. We discuss how the condition of de Sitter invariance fixes the form of the Hadamard series expansion of the Hadamard elementary function. We obtain the value of the mass scale appearing in the logarithmic term in the Hadamard series expansion. We also compare the renormalized stress tensor of conformally invariant field in the de Sitter invariant and conformal vacua.
