A method of manufacturing a tape-formed oxide superconductor, in which a tape-formed wire material ( 6 in FIG. 1 ) is extended between a pair of reels ( 5 a and 5 b). Besides, a reactive gas is supplied form the gas supply ports of a reactive gas supply pipe ( 3 a) vertically to the upper side film surface of the tape-formed wire material ( 6 ), so as to react the film body of this tape-formed wire material into a superconducting layer, while at the same time, a gas after the reaction is discharged from the gas discharge ports of discharge pipes ( 4 a and 4 b) for discharging the gas after the reaction. Likewise, the reactive gas is supplied vertically to the lower side film surface of the tape-formed wire material ( 6 ), so as to react the film body of this tape-formed wire material into a superconducting layer, while at the same time, the gas after the reaction is discharged from the gas discharge ports of discharge pipes ( 4 c and 4 d) for discharging the gas after the reaction. Even when the tape-formed wire material ( 6 ) is large in area, the tape-formed oxide superconductor has superconducting characteristics being uniform in it widthwise direction, and it can be manufactured at high speed.
