  We study again the phenomenon of charge fractionalization at finite
temperature. Our calculations are done in a framework in which the connection
between the induced fermion number and the chiral anomaly is manifest. We find
that the fractional fermion number induced on a soliton decreases as
temperature rises and vanishes at infinite temperature at one-loop level. These
results are consistent with previous studies. As an application of our
approach, we have also studied the behavior of the induced Chern-Simons term in
the (2+1)-dimensional QED at finite temperature.
