The parametrisation of the photon structure function in the low Q2 region is formulated. It includes the VMD contribution and the QCD improved parton model component suitably extrapolated to the low Q2 region. The parametrisation describes reasonably well existing experimental data on σγγ for real photons and the low Q2 data on σγ*γ. Predictions for σγγ and for σγ*γ for energies which may be accesssible in future linear colliders are also given.
