우수한 초전도 특성을 갖는 초전도 선재를 제조하기 위한 초전도 선재용 기판 및 그 제조 방법을 제공하는 것을 목적으로 한다. 최표층의 금속의 결정 배향이 c축 배향률 99% 이상이고, ΔΦ가 6° 이하이며, 또한 결정 방위가 (001)[100]에서 6° 이상 벗어나 있는 면적의 비율이 단위면적당 6% 이하인 초전도 선재용 기판. This invention provides a substrate for a superconducting wire used for manufacturing a superconducting wire with excellent superconductivity and a method for manufacturing the same. Such substrate for a superconducting wire has crystal orientation of metals on the outermost layer, such as a c-axis orientation rate of 99% or higher and a ”Õ of 6 degrees or less, and a percentage of an area in which the crystal orientation is deviated by 6 degrees or more from the (001) [100] per unit area is 6% or less.
