The entanglement of the Dirac field in the asymptotically flat black hole is investigated.Unlike the bosonic case in which the initial entanglement vanishes in the limit of infiniteHawking temperature, in this case the entanglement achieves a nonvanishing minimumvalues, which shows that the entanglement is never completely destroyed when blackhole evaporates completely. Another interesting result is that the mutual information inthis limit equals to just half of its own initial value, which may be an universal propertyfor any fields.
