发明名称 MAGNETIC ELEMENT AND METHOD OF MANUFACTURING MAGNETIC ELEMENT
摘要 There are provided a magnetic element capable of enhancing magnetic permeability of a magnetic member, improving a direct current superposition characteristic, and improving production efficiency and a method of manufacturing the magnetic element. The magnetic element includes a coil ( 30 ) formed of a conductor having an insulating film, a first core member ( 20 ) constituted of insulative soft magnetic ferrite and covering the coil ( 30 ), and a second core member ( 50 ) having soft magnetic metal powder as material and surrounded by the first core member ( 20 ). Furthermore, the magnetic element includes a third core member ( 40 ) which has soft magnetic metal powder as material and a higher filling ratio of the soft magnetic metal powder than the second core member 50 and is surrounded by the first core member ( 20 ).
