Abstract: A multilayer electronic component may include: a magnetic body in which a plurality of magnetic layers are stacked; and conductor patterns formed on the magnetic body. The magnetic body may include: metal magnetic particles; an oxide film formed on a surface of the metal magnetic particle as a first oxide obtained by oxidation of at least one component of the metal magnetic particle; and a filling portion formed in a space between the metal magnetic particles as a second oxide obtained by oxidization of at least one component of the metal magnetic particle. At least one of the first oxide and the second oxide is provided between adjacent metal magnetic particles, and an oxide film formed on a surface of a metal magnetic particle forms a neck portion with an oxide film formed on a surface of an adjacent metal magnetic particle.

Abstract: A multilayer electronic component, a manufacturing method thereof, and a board having the same. The multilayer electronic component includes a plurality of magnetic metal layers, an internal conductive layer formed on the magnetic metal layer, an upper and lower cover layers formed on and below an active part including the plurality of magnetic metal layers and internal conductive layer. The multilayer electronic component may have excellent DC bias characteristics by using a magnetic metal material, implement low direction resistance (Rdc) by increasing a cross-sectional area of an internal coil, and secure high magnetic permeability while decreasing a core loss of the magnetic metal material to thereby improve efficiency characteristic.
