Abstract: According to the latest versions of synthesis modeling of the Cosmic X-ray Background, Compton Thick AGN should represent ~50% of the total absorbed AGN population. However, despite their importance in the cosmological context, only a few dozens of Compton Thick AGN have been found and studied so far. We will briefly review this topic and discuss the improvement in this field offered by the Simbol-X mission with its leap in sensitivity (E>10 keV) of more than a factor 500 with respect to previous X-ray missions.<br />Comment: Solicited talk at the conference "Simbol-X: the Hard X-ray Universe in focus" held in Bologna, 14-16 May 2007. 8 pages, 5 figures, 2 tables
