Abstract

PURPOSE:To provide an impeder with high performance which prevents deterioration during use by using laminated bodies of amorphous metallic alloy materials as cores for the impeder. CONSTITUTION:Blocks 7 made by laminating amorphous metallic alloy materials (amorphous alloy materials) 71 by using insulating adhesives 72 are combined as cores for an impeder. Since the amorphous alloy is much stronger than magnetic metallic materials and is highly tough, they rarely deflect or buckle and are easy to handle during coating of the insulating adhesives and lamination of the blocks. Since the dimensinal accuracy of the produced foils is high and the end faces are finished smooth, there is no need for edge trimming, and the foils are easy to cut.
