  A general prescription to solve the Dirac equation in the presence of
CP-violating electroweak bubble wall is presented. The profile of the bubble
wall is not specified except that the wall height is $m_0$ and zero deep in the
broken- and the symmetric-phase regions, respectively, where $m_0$ is a fermion
mass given by the Higgs-vacuum-expectation value and the Yukawa coupling. The
CP-violating effects are evaluated by regarding CP-violating part of the bubble
wall as a perturbation to CP-conserving solutions. The basic quantity,
$R_{R\rightarrow L}-\bar R_{R\rightarrow L}$, which would contribute to the
cosmological baryon asymmetry, is estimated for some typical profiles of the
wall, where $R_{R\rightarrow L}$($\bar R_{R\rightarrow L}$) is the reflection
coefficient of right-handed chiral fermion (anti-fermion).
