Abstract. The inclusive production of prompt photons with energy above 10 GeV is measured using the OPAL detector in hadronic ${\rm Z^0}$ decays at LEP. Minimal isolation cuts were imposed upon the prompt photons. The production rate and energy spectrum of prompt photons are found to be in agreement with QCD predictions for the quark-to-photon fragmentation function.
