摘要: A high-frequency acceleration cavity core is a toroidal core obtained by winding an Fe-based magnetic ribbon having crystals with an average crystal grain size of 1 µm or less, in which a space factor of the Fe-based magnetic ribbon is 40% or more and 59% or less, and a µQf value at 1 MHz is 3 × 10 9 Hz or more. The average crystal grain size is preferably 0.1 µm or less. The toroidal core preferably has a portion having a gap portion from an inner diameter to an outer diameter.

摘要: A wound core is formed by laminating a plurality of bent bodies formed from a grain-oriented electrical steel sheet having a coating containing phosphorus formed on a surface, in a sheet thickness direction of the grain-oriented electrical steel sheet, in which the bent body is formed in a rectangular shape by having four flat portions and four corner portions adjacent to the flat portions, the corner portion has a bent region having a total bending angle of approximately 90° in a side view, the number of deformation twins present in the bent region in the side view is five or less per 1 mm of a length of a center line in the bent region in the sheet thickness direction, and the amount of phosphorus eluted from the corner portion in a case of being boiled in water for 30 minutes is 6.0 mg or less per 1 m 2 of a surface area of the corner portion.
