A stationary induction apparatus comprising: a winding (120, 130) formed of a plurality of winding layers disposed in a central axis direction; an insulating barrier (170, 270) disposed between outer peripheral ends of the winding layers adjacent to each other in the central axis direction, the outer peripheral ends being not connected to each other; and an insulating oil in which each of the winding (120, 130) and the insulating barrier (170, 270) is immersed, the insulating barrier (170, 270) including a first extension (171, 271) extending radially outwardly of the winding (120, 130) and partitioning the outer peripheral ends, a second extension (172, 272) bent from an end of the first extension (171, 271), extending toward one side in the central axis direction, and covering at least a part of one outer peripheral end of the outer peripheral ends, characterised by a third extension (173, 273) bent from an end of the second extension (172, 272) and extending radially outwardly of the winding (120, 130), and a fourth extension (174, 274) bent from an end of the third extension (173, 273), extending toward the other side in the central axis direction, and covering at least a part of the other outer peripheral end of the outer peripheral ends, the fourth extension (174, 274) facing the second extension (172, 272) with a spacing therebetween. a winding (120, 130) formed of a plurality of winding layers disposed in a central axis direction; an insulating barrier (170, 270) disposed between outer peripheral ends of the winding layers adjacent to each other in the central axis direction, the outer peripheral ends being not connected to each other; and an insulating oil in which each of the winding (120, 130) and the insulating barrier (170, 270) is immersed, the insulating barrier (170, 270) including a first extension (171, 271) extending radially outwardly of the winding (120, 130) and partitioning the outer peripheral ends, a second extension (172, 272) bent from an end of the first extension (171, 271), extending toward one side in the central axis direction, and covering at least a part of one outer peripheral end of the outer peripheral ends, characterised by a third extension (173, 273) bent from an end of the second extension (172, 272) and extending radially outwardly of the winding (120, 130), and a fourth extension (174, 274) bent from an end of the third extension (173, 273), extending toward the other side in the central axis direction, and covering at least a part of the other outer peripheral end of the outer peripheral ends, a first extension (171, 271) extending radially outwardly of the winding (120, 130) and partitioning the outer peripheral ends, a second extension (172, 272) bent from an end of the first extension (171, 271), extending toward one side in the central axis direction, and covering at least a part of one outer peripheral end of the outer peripheral ends, characterised by a third extension (173, 273) bent from an end of the second extension (172, 272) and extending radially outwardly of the winding (120, 130), and a fourth extension (174, 274) bent from an end of the third extension (173, 273), extending toward the other side in the central axis direction, and covering at least a part of the other outer peripheral end of the outer peripheral ends, the fourth extension (174, 274) facing the second extension (172, 272) with a spacing therebetween.
