We consider Vaidya's classical spacetime which represents a mass decreasing black hole by means of an inward energy flow. To consider the particle creation in such a spacetime, we try to know the change of the particle creation rate of the black hole without considering back-reaction problem. We construct a model which varies its mass like v-1 (v the usual advanced null time) to find that the particle creation in this spacetime is divergent at the final stage. This result means that a real evaporating black hole is not represented by this model, and therefore suggests that the appearance of a zero mass naked singularity cannot be avoided.
