Abstract: We present a new sample of AGNs buried in a torus with a very small opening angle selected from the XMM-Newton serendipitous source catalogue using hardness ratios. In 8/22 objects, the fraction of scattered X-ray emission from the opening part of the torus with respect to the direct emission is less than 0.5%, which is much smaller than a typical value (3%) for Seyfert 2s. Moreover, [OIII] λ5007 luminosities for our sample are smaller than those for other Seyfert 2s at a given X-ray luminosity. These results suggest that they are strong candidates of AGN buried in a very geometrically-thick torus.
