PURPOSE:To make improvement in the reliability and performance of a saturable reactor, a transformer, a saturable transformer, an accelerating cavity, a surge absorbing element such as a surge blocker for a neutral-particle beam injector and a system using these magnetic parts compatible. CONSTITUTION:In a nano-crystal soft magnetic alloy thin band, in which a fine nano-crystal particle, on a surface of which a ceramic insulating film is formed and which has particle size of 50nm or less, occupies at least 50% of a texture, the ceramic insulating film is formed in thick film thickness on the side nearer to the end section side than a central section in the cross direction of the nano-crystal soft magnetic alloy thin band, the thickness dx of the ceramic insulating film at the end section and the mean thickness da of the insulating film by a mass measuring method have the relationship of 1.2 da<=dx<=5da, and dx<=10mum holds. |
