Query: Primordial Non-Gaussianity in Multi-Scalar Slow-Roll Inflation   We analyze the non-Gaussianity for primordial curvature perturbations
generated in multi-scalar slow-roll inflation model including the model with
non-separable potential by making use of $\delta N$ formalism. Many authors
have investigated the possibility of large non-Gaussianity for the models with
separable potential, and they have found that the non-linear parameter,
$f_{NL}$, is suppressed by the slow-roll parameters. We show that for the
non-separable models $f_{NL}$ is given by the product of a factor which is
suppressed by the slow-roll parameters and a possible enhancement factor which
is given by exponentials of quantities of O(1).
