The consideration is performed in the large $N_c$ limit, where $N_c$ is the number of colored quarks. It is shown that at $L=\\infty$ ($L$ is the length of the circumference $S^1$) the pion condensation (PC) phase with {\\it zero quark number density} is realized at arbitrary nonzero $\\mu_I$ and for rather small values of $\\mu$.
