发明名称 MAGNETIC CORE AND METHOD FOR PRODUCING THE SAME
摘要 A magnetic core includes soft magnetic material particles each including a soft magnetic material and an insulating film on a surface of the soft magnetic material, the insulating film having a thickness in the range of 10 nm or more and 100 nm or less; and a binder that binds the soft magnetic material particles together and contains a non-silicate glass having a softening point in the range of 350° C. or higher and 500° C. or lower. The soft magnetic material contains an amorphous phase and has a transition temperature of 600° C. or lower at which a crystal structure changes, and the magnetic core has a resistivity of 107 Ωcm or more.
