We study dynamics of rolling tachyon and Abelian gauge field on unstable D-branes, of which effective action is given by Born-Infeld type nonlocal action. Possible cosmological evolutions are also discussed. In the Einstein frame of string cosmology, every expanding flat universe is proven to be decelerating., Comment: LaTex, 27 pages, 2 figures, Proceedings of Pac Memorial Symposium on Theoretical Physics, pp.209--239 (Chungbum Publishing House, Seoul). Talk was given by Y. Kim
