We studied the condensate mass of QCD vacuum through the duality approach via dilaton wall background in the presence of the parameter
, which represents the condensation in a holographic set up. First, from Wilson line calculation, we found
(i.e., the condensate parameter in mixed non-local condensation), whose behavior mimics that of QCD. The value of
that we found by this approach is in agreement with QCD data. Second, we considered the produced mass
via the Schwinger effect mechanism in the presence of the parameter
. We show that vacuum condensation generally contributes the mass dominantly and that the produced mass via Schwinger effect is suppressed by
.
