| description | To provide a powder magnetic core that can improve the durability against thermal shock.SOLUTION: A powder magnetic core 1 includes a plurality of iron-containing magnetic particles 2 and glass. In at least one field of view of a 500 μm×500 μm square in the cross section of powder magnetic core 1, (a) specific magnetic particles 4 having an area of 300 μm2 or more and 20000 μm2 or less, and (b) a magnetic layer 5 having thickness the size of which is 0.5 μm or more and 3 μm or less are observed, and the following specific structure 10 is observed at three or more places in the field of view. The specific structure 10 is a structure in which a plurality of magnetic layers 5 exist in a region surrounded by three or more specific magnetic particles 4, and glass exists between adjacent magnetic layers 5.SELECTED DRAWING: Figure 3
【課題】熱衝撃に対する耐久性を向上させることができる圧粉磁心を提供する。【解決手段】圧粉磁心１は、鉄含有の複数の磁性粒子２と、ガラスと、を含んでいる。圧粉磁心１の断面における５００μｍ×５００μｍの正方形の少なくとも１つの視野の中に、（ａ）３００μｍ２以上２００００μｍ２以下の面積を有する特定磁性粒子４と、（ｂ）厚さが０．５μｍ以上３μｍ以下の磁性層５と、が観察されるとともに、視野の中に次の特定構造１０が３箇所以上観察される。特定構造１０は、３つ以上の特定磁性粒子４によって囲まれた領域内に、磁性層５が複数存在し、かつ隣接する磁性層５の間にガラスが存在している構造である。【選択図】図３ |
