Abstract

A soft magnetic alloy powder has a specific composition in which a Co content is large. A soft magnetic alloy powder has a glass transition point Tg and a melting point Tm, 900° C.≤Tm≤1200° C. is satisfied, or when coercivity when applying a pressure Xto a soft magnetic alloy powder is set as Y, and a straight line obtained by linearly approximating a relationship between Xand Yby a method of least squares is set as Y=kX+1, k (unit: Oe/MPa) satisfies 0≤k≤0.00100.
