We show that, in symmetric matter, $\\Delta$ enters into matter in the density region of about one to four times of normal nuclear matter density, $\\rho_B \\sim 1 - 4\\rho_0$. The onset density of $\\Delta$ matter depends on the chiral invariant mass of $\\Delta$, $m_{\\Delta0}$: The lager $m_{\\Delta0}$, the bigger the onset density.
