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 \sim 1 keV and 200 keV .
The spectral slope is flat ( \Gamma \sim 1.6 ) , with a weak emission line at \sim 6.4 keV ( rest frame ) of EW \sim 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 \sim 0.5 keV ( observer frame ) is unambiguously detected in 3C273 .
