摘要： PROBLEM TO BE SOLVED: To provide a powder-compacted magnetic core having high magnetic flux density and low loss. SOLUTION: The powder-compacted magnetic core is obtained by compacting powder for a magnetic core composed of magnetic powder essentially consisting of Fe and Si and an insulated film formed on the surfaces of the particles of the magnetic powder.
