We investigate the Abelian dual Meissner effect due to violation of the non-Abelian Bianchi identity in SU (3) gauge thoery without gauge fixing. To decide the vacuum type, we evaluate the Ginzburg-Landau parameter from the spatial distribution of color electric fields and squared monopole density. Although the study is done only on 24 (40)3 × 4 lattice at β = 5.6, the SU (3) vacuum is found to be of the type 1 near the border of type 1 and type 2. We also confirm the dual Ampere’s law directly.
