The position sensitive neutron detector for neutron scattering experiments using intense pulsed neutron source is needed. To meet the detector performance requirements such as fast temporal response 1s, spatial resolution 1mm and detection efficiency 80 % for thermal neutron, we have been developing the micro-strip gas chamber with individual readout. In this paper, we report the simulation results of the spatial resolution of the chamber. This simulation can calculate the spatial resolution by using the distribution of neutron beam and gas condition. The simulation results agreed with the experimental data using the collimated neutron beam. In addition, the results of good uniformity about the spatial resolution and the peak counts were described.
