  We investigate the scalar perturbation in the Lee-Wick bouncing universe
driven by an ordinary scalar field plus a ghost field. We consider only a
symmetric evolution of the universe and the scalar fields about the bouncing
point. The gauge invariant Sasaki-Mukhanov variable is numerically solved in
the spatially flat gauge. We find a new form of the initial perturbation
growing during the contracting phase. After the bouncing, this growing mode
stabilizes to a constant mode which is responsible for the late-time power
spectrum.
