We analyze homogeneous, anisotropic cosmology driven by a self-interacting``massive'' antisymmetric tensor field $B_{\mu\nu}$ which is present in stringtheories with D-branes. Time-dependent magnetic $B$ field existing in the earlyuniverse can lead to the Bianchi type I universe. Evolutions of such a tensorfield are solved exactly or numerically in the universe dominated by vacuumenergy, radiation, and $B$ field itself. The matter-like behavior of the $B$field (dubbed as ``$B$-matter'') ensures that the anisotropy disappears at latetime and thus becomes unobservable in a reasonable cosmological scenario. Sucha feature should be contrasted to the cosmology of the conventional masslessantisymmetric tensor field.Comment: 13 page
