Abstract
Description
以下、本発明の一実施形態による電子部品について説明する。代表的な例としてコイル部品を選定したが、後述するFe系ナノ結晶粒合金は、コイル部品以外にも、他の電子部品、例えば、無線充電装置、フィルタなどにも適用されることができるのは明白である。
本発明の発明者らの研究によると、特定の組成のFe系ナノ結晶粒合金では、相対的に大粒径の粒子や厚さの大きい金属リボンの形態に製造する際に、母相の非晶質性が高いことが確認できた。母相の非晶質性能と飽和磁束密度に優れた合金組成の範囲が確認され、特に、Cを添加してその含量を適宜調節することで、従来よりも飽和磁束密度が向上したことが確認された。ここで、相対的に大粒径の粒子とは、D50が約20μmである場合として定義され、例えば、磁性粒子111のD50が約20〜40μmである場合に該当する。また、金属リボンの形態に製造される場合には、約20μm以上の厚さを有する場合に該当するが、直径や厚さの基準は絶対的なものではなく、状況によって変更されることができる。
101 シール材
102 支持部材
103 コイル部
111 磁性粒子
112 絶縁体
120、130 外部電極
C コア領域
