Hall effect measurements in the vortex state of the quasi two-dimensional (Q2D) organic superconductor κ-(BEDT-TTF)₂Cu(NCS)₂ are reported. The sign of the Hall conductivity changes with field and temperature in the vortex state. The Hall conductivity is described as the sum of the two terms resulting from the quasiparticle (∝ H) and the vortex motion (∝ 1/H). The sign of the latter term depends on the current direction in Q2D plane. The behavior can be explained by the anisotropic motion of the charged vortex in the anisotropic Q2D plane.
