Emission lines whose line width of  several 100 km/s
are often observed in nearby AGNs (Seyfert galaxies), which
extend from tens of parsecs to a few kiloparsecs from the nucleus.
In some nearby AGNs, they are resolved and characterized by conical
structures. I here discuss the physical origin of this emission line
region based on recent theoretical models of the ISM around
supermassive black holes.
