  Codimension-two objects on a system of brane-antibrane are studied in the
context of Born-Infeld type effective field theory with a complex tachyon and
U(1)$\times$U(1) gauge fields. When the radial electric field is turned on in
D2${\bar {\rm D}}$2, we find static regular global and local D-vortex solutions
which could be candidates of straight cosmic D-strings in a superstring theory.
A natural extension to DF-strings is briefly discussed.
