In order to provide a soft magnetic flaky powder that is used primarily in a member for an RFID and that has the high real part μ′ of a magnetic permeability and the low imaginary part μ″ of the magnetic permeability even when having an average particle diameter of 30 μm or more, and a method for producing the soft magnetic flaky powder, the present invention provides a soft magnetic flaky powder obtained by flattening-treatment of a soft magnetic powder, in which an average particle diameter is more than 30 μm, a coercive force measured by applying a magnetic field in the longitudinal direction of the flaky powder is in a range of 240 to 640 A/m, a saturation magnetization is 1.0 T or more, and an aspect ratio is 30 or more, and a method for producing the soft magnetic flaky powder.
A soft magnetic flaky powder obtained by flattening-treatment of a soft magnetic powder, wherein an average particle diameter D50 is more than 30 μm, a coercive force Hc measured by applying a magnetic field in the longitudinal direction of the flaky powder is in a range of 240 to 640 A/m, a saturation magnetization is 1.0 T or more, and an aspect ratio is 30 or more.
