- 摘要：
- A sintered ferrite material, which is obtained by adding Bi 2 O 3 in a range from 0.5 % by mass to 3 % by mass against 100 % by mass of a material having a composition formula of (1-x-y-z)(Li 0.5 Fe 0.5 )O·xZnO·yFe 2 O 3 ·zCuO wherein x, y and z satisfy 0.14‰¤x‰¤0.19, 0.48‰¤y<0.5 and 0‰¤z‰¤0.03 and satisfies resistivity equal to or higher than 10 6 ©m, initial permeability equal to or higher than 200 and saturation magnetic flux density equal to or higher than 430 mT at 23 °C and equal to or higher than 380 mT at 100 °C.
