Abstract. At the end of March 2004, the blazar S5 0716 + 714 underwent an optical outburst that prompted for quasi-
simultaneous target-of-opportunity observations with the INTEGRAL and XMM-Newton satellites. In this paper, we report the
results of the XMM-Newton and INTEGRAL OMC data analysis. The X-ray spectrum is well-represented by a concave broken
power-law model, with the break at about 2 keV. In the framework of the synchrotron self-Compton model, the softer part of the
spectrum, which is described by a power law of index α ? 1.8 (fν ∝ ν
?α
), is probably due to synchrotron emission, while the
harder part of the spectrum, which has α ? 1, is due to inverse Compton emission. The blazar shows the long and short-term
variability typical of low-frequency peaked BL Lac (LBL): the former is manifested by a gradual decrease in the optical flux
from the peak as observed by ground telescopes at the end of March 2004, while the latter is characterized by soft X-ray and
optical flares on time scales from a few thousand seconds to few hours. We can follow spectral variations on sub-hour time
