  We present initial results of computing nucleon electric dipole moment
induced by quark chromo-EDM, CP-violating quark-gluon coupling. Using
chirally-symmetric domain wall and M\"obius fermions with pion mass
$m_\pi=172\text{ MeV}$, we calculate the connected part of the electric dipole
form factor $F_3(Q^2)$. In addition, we perform an exploratory study of the
method to calculate EDM using uniform background electric field on a lattice
introduced without breaking the periodicity in the time direction.
