The direct nuclear X-ray emission of the ultraluminous IRAS galaxy NGC 6240 has been observed by BeppoSAX. It is seen through an absorber with N-H similar to 2 x 10(24) cm(-2) The 2-10 keV X-ray luminosity of > 10(44) erg s(-1) definitely proves that a powerful AGN is hosted in this galaxy, despite the LINER optical appearance. Assuming the typical L-X/L-bol ratio for quasars, our result implies that it is the AGN and not the starburst that dominates the energy output of NGC 6240
