  We proceed with the study of the Casimir force for parallel plates at finite
temperature in the Horava-Lifshitz (HL) theory. We find that the HL exponent
can not be chosen as an integer, or the Casimir energy will be a constant and
further the Casimir force between two parallel plates will vanish. The higher
temperature makes the attractive Casimir force weaker, which is consistent with
the original consequence confirmed theoretically and experimentally. We can
select the HL factor adequately to lead the thermally revised Casimir force to
be similar to the standard results for the parallel plates.
