The present invention provides an electricity generation device using a neodymium magnet having a helical structure that generates more electricity from the same torque during the same amount of time than common electricity generation devices using magnets, by helically arranging neodymium magnets, which has magnetic force significantly larger than common magnets, outside a unit coil, and that has improved performance of generating electricity by transmitting magnetic fields in vortexes to the unit coil. The electricity generation device using a neodymium magnet having a helical structure includes a first neodymium magnet, a second neodymium magnet, a third neodymium magnet, a first side magnet, a second magnet, a rod, and a unit coil. The electricity generation device using a neodymium magnet having a helical structure further includes a case, a first cover, a second cover, a cradle, a side gear, a first gear, and a handle.
