Abstract

An analyzing electromagnet constituting an ion implanter has a first inner coil, a second inner coil, three first outer coils, three second outer coils, and a yoke. The inner coils are saddle-shaped coils cooperating with each other to generate a main magnetic field which bends an ion beam in the X direction. Each of the outer coils is a saddle-shaped coil which generates a sub-magnetic field correcting the main magnetic field. Each of the coils has a configuration where a notched portion is disposed in a fan-shaped cylindrical stacked coil configured by: winding a laminations of an insulation sheet and a conductor sheet in multiple turn on an outer peripheral face of a laminated insulator; and forming a laminated insulator on an outer peripheral face.
