  We perform the potential analysis in holographic Schwinger effect in a
deformed anti-de Sitter (AdS) background with backreaction due to the gluon
condensate. We determine the potential by analyzing the classical string action
attaching on a probe D3-brane sitting at an intermediate position in the bulk
AdS space. It is found that the inclusion of the gluon condensate reduces the
production rate, reverse to the effect of the temperature. Also, we evaluate
the critical electric field by Dirac-Born-Infeld (DBI) action.
