A superconductor has a coolant passage in the internal portion to cool itself by flowing a coolant in the coolant passage. The coolant passage is formed in the stabilizing material portion in such a manner that the inner wall of the coolant passage is wave-shaped, proportion of the cross-sectional area of the coolant passage occupied in the cross-section of the superconductor is 4-22 percent, and a ratio of the circumferential length to the cross-sectional area of the coolant passage is greater 25 (cm-1).

An internal cooling type superconductor having at least one wire of superconductive material throughout its length, a stabilizer joined to the superconductive material, a coolant passage formed in the stabilizer and extending in the length direction of said superconductor forming means to pass a coolant fluid and cool said superconductor and helium within said passage, the improvement being in that a ratio of a total circumferential length of said coolant passage contacting with supercritical helium as a coolant to a total sectional area of said coolant passage is greater than 25 (cm-1), and that the total sectional area of said coolant passage is at least 4 percent of the total sectional area of said superconductor.
