It is investigated how quark confinement depends on the number of flavors, Nf, in QCD on the lattice with Wilson quarks. We strengthen and extend the conclusion reported at \it Lattice 91: (1) For Nf ≤ 6 the finite temperature deconfining transition/crossover line crosses the chiral limit at finite β. We identify the crossing point for Nf=2 and 6 on a T=4 lattice, where T is the lattice size in the temporal direction. We find the phase transition at the crossing point is continuous for Nf=2, while it is of first order for Nf=6. (2) For Nf ≥ 7, the T-independent deconfining transition observed at β=0 extends up to β=4.5 with the critical quark mass m\rm quark = O(a-1), where a is the lattice spacing.
