AB  - Inclusive production of D* mesons in deep-inelastic <i>ep</i> scattering at HERA is studied in the range 5 < Q<sup>2</sup> < 100 GeV<sup>2</sup> of the photon virtuality and 0.02 < y < 0.7 of the inelasticity of the scattering process. The observed phase space for the D* meson is p<sub>T</sub> (D<sub>*</sub>) > 1.25 GeV and  | μ(D<sub>*</sub>) |  < 1.8. The data sample corresponds to an integrated luminosity of 348 pb<sup>−1</sup> collected with the H1 detector. Single and double differential cross sections are measured and the charm contribution F<sub>2</sub><sup>c―c</sup> to the proton structure function <i>F</i><sub>2</sub> is determined. The results are compared to perturbative QCD predictions at next-to-leading order implementing different schemes for the charm mass treatment and with Monte Carlo models based on leading order matrix elements with parton showers.
