Using about 3.9 million hadronic Z decays from e+e- collisions recorded by
the OPAL detector at LEP at centre-of-mass energies near MZ the branching ratio
for the decay D_s -> tau nu_tau has been measured to be (7.0 +/- 2.1(stat) +/-
2.0 (syst))%. This result can be used to derive the decay constant of the D_s
meson: f(D_s) = 286 +/- 44(stat) +/- 41(syst) MeV.
