In a high-temperature superconductive conductor winding (1) comprising a tape-shaped high-temperature superconducting wire (2) which is combined with a metal 5 and wound into the form of a double pancake coil, the length of a throughout portion (5) provided between pancakes (4, 6) is at least four times the width of the tape-shaped high-temperature superconducting wire. Thus, it is possible to suppress generation of shearing stress at 10 the throughout portion (5), thereby preventing reduction of the critical current density caused by such shearing stress.
