LAMINATED ELECTRONIC COMPONENT |
摘要 |
<p>A laminated electronic component having an excellent DC superimposition property. Coil electrodes (18a to 18c) are connected with one another to constitute a coil (L). A plurality of magnetic layers (16a to 16k) are laminated with the coil electrodes (18a to 18c). Nonmagnetic layers (20a, 20b) are formed outside a region (a) surrounded by the coil electrodes (18a to 18c) when viewing from the laminating direction but inside a range (ß) in which the coil electrodes (18a to 18c) are formed in the laminating direction. Low magnetic permeability layers (22a to 22c) are formed inside the scope (a) surrounded by the coil electrodes (18a to 18c) when viewing from the laminating direction and inside the scope (ß) in which the coil electrodes (18a to 18c) are formed in the laminating direction. The low magnetic permeability layers are formed of material having a magnetic permeability lower than that of the magnetic layers (16a to 16k).</p> |
