PURPOSE:To insulate between thin belts by folding a belt type insulator between wound amorphous magnetic alloy thin belts and cool thin belt with the liquid passing the space between thin belts. CONSTITUTION:A wound core is formed in such a condition that a plurality of amorphous magnetic alloy thin belts 1 are laminated into a layer. The belt type insulators 2 are folded in the direction of winding radius at a plural areas with adequate interval in the winding direction of thin belts 1. In this case, the insulator 2 is folded changing the direction alternately at the edge part of each layer of thin belt 1 and is folded in the same direction through each layer of thin belt 1. Thereby, a space in the width corresponding to the thickness of insulator 2 is generated between layers of thin belts 1 and this space is partitioned by the insulator 2 provided with adequate interval. The void 3 is formed between layers of partitioned thin belts 1. |
