  We report the detection of an X-ray absorption feature near the galaxy M86 in
the Virgo cluster. The absorber has a column density of 2-3 E20 /cm^2, and its
position coincides with the peak of an intracluster HI cloud which was removed
from the galaxy NGC 4388 presumably by ram pressure. These results indicate
that the HI cloud is located in front of M86 along the line-of-sight, and
suggest that the stripping was primarily created by an interaction between NGC
4388 and the hot plasmas of the Virgo cluster, not the M86 halo. By calculating
an X-ray temperature map, we further detected an X-ray counterpart of the HI
cloud up to about 3' south of M86. It has a temperature of 0.89 keV and a mass
of ~4.5 E8 solar mass, exceeding the estimated HI gas mass. The high
hot-to-cold gas ratio in the cloud indicates a significant evaporation of the
HI gas, probably by thermal conduction from the hotter cluster plasma with a
sub-Spitzer rate.
