  After making an abelian projection in the maximally abelian gauge, we measure
the distribution of abelian electric flux and monopole currents around an
abelian Wilson loop in $SU(2)$ and $SU(3)$ QCD. The (dual) Meissner effect is
observed clearly. The vacua in the confinement phases of $SU(2)$ and $SU(3)$
are both at around the border between type-1 and type-2 (dual) superconductor.
