An expectation value of the energy-momentum tensor for a massive scalar
field propagating in a Robertson-Walker universe is calculated by taking
account of both effects caused by the particle creation and the vacuum
polarization. A special case of the Chitre-Hartle universe which enables
us to perform an explicit calculation is also treated.
