  We report the results of 3D spectroscopic observations of Mrk 493 (NLS1
galaxy) with the integral-field spectrograph MPFS of the SAO RAS 6-m telescope.
The difference in the slope of the optical continuum emission intensity across
the nucleus part and an extensive continuum emission region} is detected. The
emission in lines (H$\alpha$, H$\beta$, [OIII], etc.) coincides with a
composite nuclear region: an AGN plus a circum-nuclear star-forming ring
observed in the HST UV/optical images. The [SII] emission region tends to be up
to 1kpc around the center. The H$\alpha$ and H$\beta$ could be decomposed into
three components (broad $\sim$ 2000 km/s. intermediate $\sim$ 700 km/s and
narrow $\sim$ 250 km/s). We found that width ($\sim$ 750 km/s) of the Fe II
lines correspond to the intermediate component, that may indicate a non-BLR
origin of the Fe II lines, or that a large fraction of the Fe II emission arise
in the outher parts of the BLR. The weak broad component detected in the
H$\alpha$, H$\beta$ and He$\lambda$4686 may come from the unresolved central
BLR, but also partly produced by violent starburst in the circum-nuclear ring.
Moreover, diagnostic diagrams clearly show presence of the HII regions (not a
Sy 1 nucleus) in the NLR of Mrk 493.
