The one-loop contributions to the entropy for a massive scalar field in a Kerr black hole are investigated using an approximation of the metric, which, after a conformal transformation, permits one to work in a Rindler-like space-time. Of course, as for the Schwarzschild case, the entropy is divergent in the proximity of the event horizon.
