The design is based on a "nano-beam scheme", where vertical beam size is squeezed into 50 nm at an interaction point. One of key component is a final focus magnet system. The focusing system consists of 4-superconducting (SC) quadrupole doublets, 43 SC-correctors, 4 SC-compensation solenoids. They are aligned in a detector (Belle-II) solenoid which generates a longitudinal field of 1.5 T. The system are packed in a small area and also has magnetic shields. So it is expected an entire magnetic field of the system is not one which is linearly-superimposed field of each magnet. Here a study of three dimensional field analysis for the final focus magnet system will be presented.
