PROBLEM TO BE SOLVED: To provide a superconducting coil apparatus capable of suppressing quench without reducing coil performance. SOLUTION: A superconducting coil apparatus 1 includes a conducting part 12 consisting of a superconducting line material 13 wound in a solenoid shape, and has: a main coil 10 that generates a magnetic field in a specified direction along an axial direction of the conducting part 12; and an inverse magnetic field coil 20 provided at a position of a diameter direction outside of the main coil 10 on the same axis of the main coil 10. The inverse magnetic field coil 20 consists of: a winding frame 21 provided at a position separated from the conducting part 12 to the diameter direction outside so as to face the periphery of the conducting part 12 and which has a cylindrical peripheral surface 21c; and a conducting part 22 consisting of a superconducting line material 23 wound to the peripheral surface 21c of the winding frame 21 in a solenoid shape and which carries electricity in an inverse direction to the conducting part 12 in a circumferential direction to generate inverse magnetic field to the specified direction in a region of diameter direction inside.
