Add to ORKGUsing the ARGUS detector at the e"+e"- storage ring DORIS II, we have searched for the real and imaginary part of the electric dipole formfactor d_#tau# of the #tau# lepton in the production of #tau# pairs at q"2=100 GeV"2. This is the first direct measurement of this CP violating formfactor. We applied the method of optimised observables which takes into account all available information on the observed #tau# decay products. No evidence for CP violation was found, and we derive the following results: Re(d_#tau#)=(1.6#+-#1.9).10"-"1"6 ecm and Im(d_#tau#)=(-0.2#+-#0.8).10"-"1"6 ecm, where statistical and systematic errors have been combined.
