We report a measurement of the electric dipole moment of the $τ$ lepton $(d_{τ})$ using an 833 fb$^{−1}$ data sample collected near the $Υ(4S)$ resonance, with the Belle detector at the KEKB asymmetric-energy e$^{+}$e$^{−}$ collider. Using an optimal observable method, we obtain the real and imaginary parts of $d_{τ}$ as Re(d$_{τ}$) = (−0.62 ± 0.63) × 10$^{−17}$ecm and Im($d_{τ}$) = (−0.40 ± 0.32) × 10$^{−17}$ecm, respectively. These results are consistent with null electric dipole moment at the present level of experimental sensitivity and improve the sensitivity by about a factor of three.[graphic not available: see fulltext
