Document Type and Number:
WIPO Patent Application WO/2018/159610
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a soft magnetic flat powder having high magnetic permeability and high weather resistance; a soft magnetic resin composition containing the soft magnetic flat powder; and a magnetic sheet. In order to achieve the purpose, provided is a soft magnetic flat powder which is an aggregate of a plurality of soft magnetic flat particles, wherein each of the plurality of soft magnetic flat particles comprises an Fe-Si-Al-based flat particle and a coating layer formed on the surface of the Fe-Si-Al-based flat particle, and the total C amount (mass%) contained in the coating layer of the plurality of soft magnetic flat particles/the BET specific surface area (m2/g) of the soft magnetic flat powder is 0.01-1.00 (mass%·g/m2).
