The newly observed isomer and ground-state band in the odd-Z neutron-rich rare-earth nucleus 163 Eu are investigated by using the cranked shell model (CSM), with pairing treated by the particle-number conserving (PNC) method. This is the first time detailed theoretical investigations are performed of the observed 964 (1) keV isomer and ground-state rotational band in 163 Eu. The experimental data are reproduced very well by the theoretical results. The configuration of the 964 (1) keV isomer is assigned as the three-particle state $\displaystyle\frac {13}{2}^{-}\left (\nu\displaystyle\frac {7}{2}^{+}[633]\otimes\nu\displaystyle\frac {1}{2}^{-}[521]\otimes\pi\displaystyle\frac {5}{2}^{+}[413]\right) $
