It is a problem to provide a quench-free superconducting coil and a magnetic resonance imaging apparatus that reduce Joule heat generated by peeling between members even in a high magnetic field. A superconducting coil according to the present invention includes a winding frame and a superconducting wire wound around the winding frame, and a first resin layer including a thermoplastic resin between the winding frame and the superconducting wire. A second resin layer containing a thermosetting resin, and a mixed layer located between the first resin layer and the second resin layer and containing a mixture of the thermoplastic resin and the thermosetting resin； Have高磁場においても、部材間の剥離により発生するジュール熱を低減し、クエンチフリーな超電導コイル及び磁気共鳴イメージング装置を提供することが課題である。本発明に係る超電導コイルは、巻枠と、前記巻枠に巻きつけられた超電導線とを有し、前記巻枠と前記超電導線との間に、熱可塑性樹脂を含む第１の樹脂層と、熱硬化性樹脂を含む第２の樹脂層と、前記第１の樹脂層と前記第２の樹脂層の間に位置し、前記熱可塑性樹脂と熱硬化性樹脂の混合物を含む混合層と、を有する。
