To provide a superconducting coil in which occurrence of quench is suppressed.SOLUTION: A superconducting coil includes a winding frame, a superconducting wire material which is wound around the winding frame and has a first region and a second region facing the first region in a coil diameter direction, and a resin layer which is positioned between the first region and the second region, and includes particles, an epoxy resin surrounding the particles, and a region including silane including a phenylamino group existing between the particles and the epoxy resin. An average particle diameter of the particles is 1 μm or more and 5 μm or less, and a volume ratio of the particles in the resin layer is 50% or more and 66% or less.SELECTED DRAWING: Figure 5 【課題】クエンチの発生が抑制された超電導コイルを提供する。【解決手段】実施形態の超電導コイルは、巻枠と、巻枠に巻き回され、第１の領域と、第１の領域にコイル径方向において対向する第２の領域を有する超電導線材と、第１の領域と第２の領域との間に位置し、粒子と、粒子を囲むエポキシ樹脂と、粒子とエポキシ樹脂との間に存在するフェニルアミノ基を含むシランを含む領域と、を含む樹脂層と、を備える。そして、粒子の平均粒径は、１μｍ以上５μｍ以下であり、樹脂層における粒子の体積割合は５０％以上６６％以下である。【選択図】図５
