A search for mixing in the neutral D meson system has been performed using semileptonic D-0 -> K((*)-)e(+)nu decays. Neutral D mesons from D*+-> D-0 pi(+) decays are used; the flavor at production is tagged by the charge of the slow pion. The measurement is performed using 253 fb(-1) of data recorded by the Belle detector. From the yield of right-sign and wrong-sign decays arising from nonmixed and mixed events, respectively, we estimate the upper limit of the time-integrated mixing rate to be r(D)< 1.0x10(-3) at 90% C.L.
