  Superconductivity or metallic state may coexist with density wave ordering at
imperfect nesting of the Fermi surface. In addition to the macroscopic spatial
phase separation, there are, at least, two possible microscopic structures of
such coexistence: (i) the soliton-wall phase and (ii) the ungapped
Fermi-surface pockets. We show that the conductivity anisotropy allows to
distinguish between these two microscopic density-wave structures. The results
obtained may help to analyze the experimental observations in layered organic
metals (TMTSF)$_{2}$PF$_{6}$, (TMTSF)$_{2}$ClO$_{4}$, $\alpha
$-(BEDT-TTF)$_{2}$KHg(SCN)$_{4}$ and in other compounds.
