An exact solution for the thick domain wall in Lyra geometry is found. The energy
density decreases on both sides of the wall and space-time is reflection symmetric with
respect to the wall. The space-time shows that the thick domain wall will not collapse. It
is shown that the gravitational field experienced by a test particle is repulsive.
