To resolve an error magnetic field so as to reliably prevent diffusion of a charged particle beam flowing in a beam line of a charged particle accelerator.
In a superconducting coil device 10 for using a superconductive electromagnet with two or more electrodes fitted at the beam line of the charged particle accelerator, a correcting magnetic field coil 13 capable of forming a magnetic field for canceling the error magnetic field generated by an electromagnet containing a main magnetic field coil 12 is arranged independent from an outer ambient of the coil 12. The correcting magnetic field coil 13 corresponds to the error magnetic field generated by the electromagnet containing the main magnetic field coil 12 to set at least either the number of poles of the coil, the shape, the number of turns or the setting position.
