  We consider ``brane universe'' with nonzero tension in the models with large
extra dimensions. We find exact solutions of higher-dimensional Einstein
equations with single flat Minkowsky brane of arbitrary large tension (or brane
cosmological constant) and compact extra dimensions. The brane curves the bulk
space-time in a small region around it. There is no fine tuning of energy
scales in our model.
