PROBLEM TO BE SOLVED: To provide a superconducting coil device for suppressing heat generation at a connection between a superconducting coil and an electrode and for preventing the superconducting coil from producing a bending stress. SOLUTION: The superconducting coil device includes: a superconducting coil wound with a tape-shaped superconducting wire material 5; a bobbin 3 having a body portion 3a disposed on the internal circumference of the superconducting coil and a flange portion 3b projecting from one end of the body portion in the axial direction; a first electrode 10 connected to an end portion of the superconducting wire material 5 of the superconducting coil; and a second electrode 11 integrated with the first electrode. The first electrode 10 is shaped to have a circular arc-shaped contact portion 20 extending in the circumferential direction along the end portion of the superconducting wire material of the superconducting coil and a fixing portion 21 for fixing to the flange portion 3b on one end side in the circumferential direction of the circular arc-shaped contact portion and projecting from the flange portion. The second electrode 11 is shaped to project outwardly from the flange 3b and have a connection with a power supply cable 6. The circular arc-shaped contact portion 20 of the first electrode is soldered to the end portion of the superconducting wire material. COPYRIGHT: (C)2010,JPO&INPIT |
