We systematically investigate the possibility of finding CP/T violation inthe $\tau$ sector at Tau-Charm Factory. CP/T violation may occur at $\tau$ pairproduction process, expressed as electric dipole moment, and at $tau$ decayprocesses. By assuming that electric dipole moment as large as $10^{-19}$e-cmand CP/T violation effect orignating from $\tau$ decay as large as $10^{-3}$are observable at Tau-Charm Factory, we studied all the possible extensions ofthe SM which are relevent for generating CP/T violation in $\tau$ sector. Andwe pointed there are a few kind of models, which are hopeful for generatingsuch CP/T violation. For these models we consider all the theoretical andcurrent experimental constraints and find that there exists some parameterspace which will result in a measurable CP/T violation. Therefore we concludethat Tau-Charm Factory is a hopeful place to discover CP/T violation in $\tau$sector.Comment: 30 pages, 2 figures in ps file
