We have studied composite on the base of nanoporous glass into the pores of which palladium particles (about 10% of the pore volume) are embedded, and the remaining space is filled with ferroelectric – sodium nitrite. The temperature and frequency dependences of the dielectric response for the nanocomposite with metal particles and without it were measured and analyzed. The Pd-NaNO2 nanocomposite (metal – ferroelectric) created was found to have high effective dielectric permittivity (up to 10^9). DC-conductivity of the composite with metal particles was more than an order of magnitude greater than that of pure sodium nitrite in the porous glass, due, apparently, to the appearance of additional electronic conductivity.
