  The unusual phase has been recently observed in the organic material
(TMTSF)$_{2}$PF$_{6}$, where superconductivity (SC) coexists with spin-density
wave (SDW) in the pressure interval $p_{c1}<p<p_{c}$ below the first order
transition into SC or normal metal phase. Assuming that the coexistence takes
place on the microscopic scale, we consider the properties of the intermediate
phase. We show that the new superconducting state inside SDW phase just above
$p_{c1}$ must bear a triplet pairing.
