Including fluctuations of the superfluid order parameter within the strong-coupling theory developed by Nozi\\`eres and Schmitt-Rink, we calculate the temperature dependence of $C_{\\rm V}$ at the unitarity limit in the superfluid phase. We show that, in the low temperature region, $T^3$-behavior is shown in the temperature dependence of $C_{\\rm V}$.
