We analyze the B anomalies associated with the B→ D(*)τν decays in the unparticle model. The fraction of the branching ratios R(D(*)) and other parameters related to the polarization are fitted to the experimental data by minimizing χ2. The best-fit values are R(D)\rm best=0.371 and R(D^*)\rm best=0.266 which are still larger than the standard model predictions. We find that our results safely render the branching ratio \rm Br(Bc→τν) below 10%.
