[en] We present the first results of numerical test of the Kugo-Ojima confinement criterion in the lattice Landau gauge. The Kugo-Ojima criterion of colour confinement in the BRS formulation of the continuum gauge theory is given by u^a_b(0) = -δ^a_b, where ∫dxe^ip(x-y)<0 vertical bar TD_μc^a(x)g(A_νxc-bar)^b(y) vertical bar 0> (g_μν-(p_μp_ν/p²) )u^a_b(p²). (*) We measured the lattice version of u^a_b (0) in use of 1/(-∂D(A)) where D_μ(A) is a lattice covariant derivative in the new definition of the gauge field as U e^A. We obtained that u^a_b (0) is consistent with -cδ^a_b, c = 0.7 in SU(3) quenched simulation data of β = 5.5, on 8⁴ and 12⁴. We report the β dependence and finite-size effect of c
