摘要：

We investigate the confinement properties in the multi-instanton system, where the size distribution is assumed to be rho(-5) for the large instanton size rho. We find that the instanton vacuum gives the area law behavior of the Wilson loop, which indicates existence of the linear confining potential. In the multi-instanton system, the string tension increases monotonously with the instanton density, lid takes the standard value sigma similar or equal to 1 GeV/fm for the density (N/V)(1/4) = 200MeV. Thus, instantons directly relate to color confinement properties.
