The observation of the Narrow-Line Seyfert 1 galaxy IRAS 13349+2438 performed by XMM-Newton European Photon Imaging Camera between 0.3-10keV, is presented here. The broadband spectrum of the source is dominated at low energies (E≤2keV) by a strong excess of emission and by complex emission/absorption features between ∼5.5-8.0keV. The soft X-ray spectrum is consistent with ionized absorption found by the Reflection Grating Spectrometer (Sako et al., 2001A&A...365L.168S). We focus on the 2-10keV spectrum which shows clear evidence for a broad, complex FeKα line, previously unseen by ASCA, and for an Fe K-shell edge detected at ∼7.3-7.4keV (rest-frame). The presence of this edge could be explained by either partial covering or ionized/relativistic reflection models, with the latter being preferred and with a resulting power law slope of Γ∼2.2. The line profile is complex, with a broad bump between ∼5.5-6.5keV and a narrow emission line at ∼7keV, separated by a sharp drop at ∼6.8keV. This profile is compatible with two possible scenarios: I) a broad, ionized and gravitationally redshifted Laor diskline plus a narrow and ionized emission line; II) a broad, ionized and single Schwarzschild (double-peaked) diskline with a superimposed narrow absorption line.
