Abstract: Inclusive production of D* mesons in deep-inelastic $\it ep$ scattering at HERA is studied in the range 5 < $Q^{2}$ < 100 $GeV^{2}$ 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 $p_{T}$ $(D_{*})$ > 1.25 GeV and $\mid\mu(D_{*})\mid$ < 1.8. The data sample corresponds to an integrated luminosity of 348 $pb^{−1}$ collected with the H1 detector. Single and double differential cross sections are measured and the charm contribution $F_{2}^{c\bar{c}}$ to the proton structure function $\it F_{2}$ 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.
