  We have performed a two-dimensional spectroscopy of three nearby E+A
(post-starburst) galaxies with the Kyoto3DII integral field spectrograph. In
all the cases, Hdelta absorption is stronger at the centre of the galaxies, but
significantly extended in a few kpc scale. For one galaxy (J1656), we found a
close companion galaxy at the same redshift. The galaxy turned out to be a
star-forming galaxy with a strong emission in Hgamma. For the other two
galaxies, we have found that the central post-starburst regions possibly extend
toward the direction of the tidal tails. Our results are consistent with the
merger/interaction origin of E+A galaxies, where the infalling-gas possibly
caused by a galaxy-galaxy merging creates a central-starburst, succeeded by a
post-starburst (E+A) phase once the gas is depleted.
