In this paper, we consider the D-brane, especially the Dက-brane, in the parallel plane(pp)-wave
background, which has eight dynamical and the eight kinematical supercharges. Since the pp-wave
background is not a SO(8), but a SO(4)SO(4) symmetric group, the D-brane world-volume theory
has a non-trivial symmetric group that depends on the conguration of the D-brane. Here, we will
analyze the open string spectrum consistent with the non-trivial symmetric group and, at the lowenergy
limit, classify the eld contents of the D-brane world-volume theory which come from the
fermionic zero-modes of the open string.
