  The magnetic susceptibility of the organic superconductors $\kappa$-(h8 or
d8-ET)$_{2}$$X$, $X =$ Cu(NCS)$_{2}$ and Cu[N(CN)$_{2}$]Br has been studied. A
metallic phase below $T^{*} =$ 37 $\sim$ 38 K for $X =$ Cu[N(CN)$_{2}$]Br and
46 $\sim$ 50 K for $X =$ Cu(NCS)$_{2}$ has an anisotropic temperature
dependence of the susceptibility and the charge transport. Partial
charge-density-wave or charge fluctuation is expected to coexist with the
metallic phase instead of the large antiferromagnetic fluctuation above
$T^{*}$. The phase diagram and the superconductivity of $\kappa$-(ET)$_{2}$$X$
are discussed in connection with this phase.
