We report the transport properties in the quantum vortex liquid (QVL) state of the layered organic superconductor κ-(BEDT-TTF)2Cu(NCS)2. A steep change of the resistivity in the vortex liquid state is observed below about 1 K. In the low resistance state at lower temperatures, finite resistivity persists at least down to 100 mK. The finite residual resistivity may result in QVL assisted by the strong quantum fluctuations. A non-ohmic behavior appears only in the low resistance state, but not in the thermal vortex liquid state at high temperatures. These transport properties are similar to the observations discussed as the vortex slush state in the high-Tc oxides.
