Abstract :  We consider the open superstring action in AdS_5 x S^5 background with the bilinearWess-Zumino term, which has been modified in such a way that a certain total divergence term is absent,
and give the covariant description of supersymmetric D-branes.  We show that the modification of bilinear
Wess-Zumino term is necessary to describe correctly the 1/2-BPS D-instanton in AdS_5 x S^5
background, while the classification of other supersymmetric D-branes does not depend on such modification.
