PURPOSE:To improve the cooling performance of a wire rod for superconductive magnet for generating the high magnetic field by applying an insulating material with the withstand voltage of 500V or less to the wire rod for superconductive magnet using a specific ceramic oxide superconductive material as a component element. CONSTITUTION:A ceramic oxide superconductive material containing the IIa group element and IIIa group element in the periodic table, copper, and oxygen is used. An insulating material with the withstand voltage of 500V or less is formed on a superconductive magnet wire rod with such constitution for use as the superconductive magnet wire rod for generating the high magnetic field in particular. When the superconductive material with such a high critical temperature is used, the requirement for the high withstand voltage is eliminated, and the cooling performance can be improved. In addition, the current density is increased, and a coil is made small-sized. |
