We study a black hole domain wall system in dilaton gravity, which is the low-energy limit of superstring theory. We solve numerically equations of motion for a real self-interacting scalar field and justify the existence of a static axisymmetric field configuration representing a thick domain wall in the background of a charged dilaton black hole. It is also confirmed that the extreme dilaton black hole always expels the domain wall.
