PROBLEM TO BE SOLVED: To provide a laminated superconducting coil device which suppresses displacement of a plurality of laminated high-temperature superconducting coils from a specific position and of which a part can be easily exchanged.SOLUTION: The laminated superconducting coil device comprises: a winding member 12 in which a plurality of superconducting coils 11 are laminated in a winding axis direction C, the superconducting coil being formed by winding a high-temperature superconducting wire 20; a cylindrical material 35 which is disposed along an innermost peripheral surface of the superconducting coils 11 and penetrates the winding member 12 in the winding axis direction C; a flange 33 fixed to the cylindrical material 35 so as to oppose at least one of end faces 32 of the winding member 12 in the winding axis direction C; and an abutment member 34 which is fixed to the flange 33 in a movable manner in the winding axis direction C and abutted to the end face 32. At least a part of a contact plane 41 of the laminated superconducting coil 11 in contact with the other neighboring high-temperature superconducting coil is non-adhered or weakly adhered by mold release processing.SELECTED DRAWING: Figure 3 【課題】積層された複数の高温超電導コイルの規定位置からのずれを抑制させるとともにその一部を容易に交換することが可能な積層型超電導コイル装置を提供する。【解決手段】高温超電導線材２０が巻回されてなる超電導コイル１１が巻回軸方向Ｃに複数積層された巻線部材１２と、超電導コイル１１の最内周面に沿って配置されて巻線部材１２を巻回軸方向Ｃに貫通する筒材３５と、巻線部材１２の巻回軸方向Ｃの端面３２の少なくとも一面に対向するように筒材３５に固定されるフランジ３３と、フランジ３３に巻回軸方向Ｃに可動に固定されて端面３２に押し当てられる押当て部材３４と、を備え、積層される超電導コイル１１の隣接する他の高温超電導コイルと接触する接触面４１の少なくとも一部を非接着または離形処理による弱接着にする。【選択図】 図３
