  We report the results of a 3C273 observation performed during the Science
Verification Phase (SVP) of the BeppoSax satellite. The broad-band spectrum is
well represented by a power-law between 1 keV and 200 keV. The spectral slope
is flat (\Gamma ~1.6) with a weak emission line at ~ 6.4 keV (rest frame) of EW
~ 30 eV. Below 1 keV, a deviation from a power-law due to an absorption feature
plus a soft component is present. This is the first time that a feature in
absorption at ~ 0.5 keV (observer frame) is unambiguously detected in 3C273.
