Magnetic material and electronic component
A magnetic material has: multiple soft magnetic alloy grains that contain Fe, element L (where element L is Si, Zr, or Ti), and element M (where element M is not Si, Zr, or Ti, and oxidizes more easily than Fe); a first oxide film that contains element L and covers each of the multiple soft magnetic alloy grains; a second oxide film that contains element M and covers the first oxide film; a third oxide film that contains element L and covers the second oxide film; a fourth oxide film that contains Fe and covers the third oxide film; and bonds that are constituted by parts of the fourth oxide film and that bond the multiple soft magnetic alloy grains together.
