The present status of the photon structure functions measurements at LEP is discussed. The short introduction to the kinematics and theoretical framework of the structure functions measurements at LEP is given first. Then follow presentations of the most important measurements, ranging from the QED photon structure function, through the hadronic structure functions of real and virtual photons, and at the end the first measurement of the electron structure function is shown.
