Blazars are the most numerous class of extragalactic γ-ray sources. Because of their very broad spectral emission, blazars are expected to play an important role in the generation of the extra-galactic background in several energy bands. Using the Palermo BAT survey archive we searched for the hard X-ray counterparts of the ∼2600 objects in the Roma-BZCAT Blazars catalogue to study their contribution to the 15-150 keV extragalactic emission.
