MAGNETIC MATERIAL AND COIL COMPONENT USING SAME |
摘要 |
The issue of the invention is to provide a novel magnetic material combining both improved insulation resistance and improved magnetic permeability, and also to provide a coil component using such a magnetic material. Provided is a magnetic material according to the present invention which comprises a particle moulding (1) that is provided with: a plurality of metal particles (11) made of Fe-Si-M-based soft magnetic alloy (where M is a metal element that is more easily oxidized than Fe); and an oxide coating (12) formed on the surfaces of the metal particles. The particle moulding (1) has: bonding portions (22) by way of the oxide coating (12) formed on the surfaces of adjacent metal particles; and bonding portions (21) of metal particles (11) in portions where no oxide coating (12) is present. |
