Résumé : The hadronic photon structure function F2γ(x, Q2) is measured from data taken with the ALEPH detector at LEP. At centre-of-mass energies between √s = 189 GeV and 207 GeV an integrated luminosity of 548.4 pb-1 is analyzed in two ranges of Q2 with 〈Q2〉 = 17.3 GeV2 and 67.2 GeV2. Detector effects and acceptance are corrected for with a Tikhonov unfolding procedure. The results are compared to theoretical predictions and measurements from other experiments.
