More Information
Summary:As a soft magnetic metal powder including a plurality of soft magnetic metal particles composed of Fe-based nanocrystalline alloy including Cu, the soft magnetic metal particles have a core part and a first shell part surrounding the core part, an average crystallite diameter of a Cu crystallite present in the core part is set to be A, and B/A is greater than or equal to 3.0 and less than or equal to 1000 when a maximum crystallite diameter of the Cu crystallite in the first shell part is B. Therefore, the present invention is capable of having a good withstanding voltage resistance. Cu를 포함하는 Fe계 나노 결정 합금으로 구성되는 연자성 금속 입자를 복수 포함하는 연자성 금속 분말로서, 연자성 금속 입자는, 코어부와, 코어부의 주위를 둘러싸는 제1 셸부를 갖고, 코어부에 존재하는 Cu 결정자의 평균 결정자 직경을 A로 하고, 제1 셸부에 존재하는 Cu 결정자의 최대 결정자 직경을 B로 한 경우, B/A가 3.0 이상 1000 이하인 것을 특징으로 하는 연자성 금속 분말이다.
