Abstract
A soft magnetic metal powder includes a plurality of soft magnetic metal grains composed of an Fe—Si based alloy. A content of P in the Fe—Si based alloy is 110 to 650 ppm provided that a total content of Fe and Si is 100 mass %. A soft magnetic metal fired body includes soft magnetic metal fired grains composed of an Fe—Si based alloy. A content of P in the Fe—Si based alloy is 110 to 650 ppm provided that a total content of Fe and Si is 100 mass %.
