Abstract:
We discuss the abundance of Compton-thick AGN as estimated by the most
recent population synthesis models of the cosmic X-ray
background. Only a small fraction of these elusive objects have been
detected so far, in line with the model expectations. The advances
expected by the broad band detectors on board Suzaku are briefly
reviewed.
