摘要： A method for manufacturing an oxide superconducting coil can suppress deterioration of superconducting characteristics caused by a strong electromagnetic force and deformation and a reaction during heat treatment. The oxide superconducting coil is manufactured by a wind-and-react (W&R) method using a metal sheathed oxide superconducting wire material and an insulator, wherein an oxide film formed on a surface of a heat resistant alloy during a heat treatment is used for insulating the coil, and the heat resistant alloy has a sufficient strength to prevent the deformation of the coil generated by the weight of the coil itself during the heat treatment and to endure a strong electromagnetic force. An oxide superconducting coil operable with a coolant, such as liquid nitrogen, liquid helium, and the like, or a refrigerator, can be realized.
