Abstract
We report results on the first search for direct CP violation in the tau se mi-leptonic decay tau (+/-) --> pi (+/-)pi (o)nu (tau). A difference of tau (+) and tau (-) decay angular distribution is examined using a data sample of 6.7fb(-1) recorded with the Belie detector at the KEKB e (+) e (-) coll ider. No CP violation is observed. An upper limit at the 1% level is set on the CP asymmetry.
