We present the search of time-dependent CP asymmetries with the charmless hadronic B -> eta' Ks decay sample taken at the KEKB asymmetric energy e+e- collider with the Belle detector. While one B is reconstructed as the CP eigenstate eta'Ks, the flavor of accompanying B meson is investigated by its decay daughters. We report the CP violation coefficients of sine(S{eta'Ks}) and cosine(A{eta'Ks}) term: S{eta'Ks} = 0.28 {+-0.55} {+0.07 / -0.08}, A{eta'Ks} = 0.13 {+-0.32} {+0.09 / -0.06}.
