We study the hadron-quark phase transition with finite size effects at a finite temperature. For the hadron phase, we adopt a realistic equation of state with the Brueckner-Hartree-Fock theory including hyperons. Properties of the mixed phase are clarified by considering the finite size effects under the Gibbs conditions. We find that the equation of state gets closer to that given by the Maxwell construction. We also find that the equation of state becomes softer than that at a zero temperature for some density region. Moreover, the number of hyperons is suppressed by the presence of quarks. These are characteristic features of the hadron-quark mixed phase, and should be important for many astrophysical phenomena such as mergers of binary neutron stars.
