The chiral phase transition of the quark matter is studied in the
framework of the QCD-like gauge field theory. The thermodynamical
potential is investigated using a variational approach. Latent heat
generated in the first-order phase transition is calculated and it
is shown that the latent heat is enhanced near the tricritical point
and is more than several hundred MeV per quark.
