The differential cross section and target asymmetry components of the reaction D(e,pp)e'pi- on polarized deuteron were measured. The kinetic energies of the protons were measured within 55-180 MeV and 46-265 MeV. The polar acceptance angles in laboratory frame for the both protons are (64 - 82) degrees and the azimuthal angles are (-16 +16), (164 - 196) degrees. The sharp peak of the tensor a(20)-component of the target asymmetry is found near the invariant mass of the pppi-system M(pppi) = 2300 MeV/c**2. The performed calculations of the differential yield and the tensor target asymmetry do not describe the obtained experimental results.
