- FIGS. 1 to 3 See the first embodiment, FIGS. 1 to 3)
- the multilayer coil 1 has an inner-layer ceramic green sheet 13 provided with a plurality of coil conductor patterns 9, lead-out conductor patterns 11 and via holes 7 for interlayer connection, and Ceramic green sheet 15 for inner layer provided with via hole 7, ceramic green sheet 14 for inner layer provided with conductor patterns 10 for coil and lead-out conductor pattern 11, and ceramic for outer layer It is composed of green sheets 16 and others.
- the ceramic green sheets 13 to 16 are prepared by kneading Fe-Ni-Cu-based ferrite powder or dielectric powder together with a binder, for example, by a doctor blade method or the like. It is made into a shape.
- the coil conductor patterns 9, 10 and the lead conductor pattern 11 are made of Ag, Pd, Cu, Au, or an alloy thereof, and are formed by a method such as screen printing.
- a via hole 7 for interlayer connection, which is a conductor for the coil, is formed using a laser beam or the like. By filling It is formed.
- the coil conductor patterns 9 and the coil conductor patterns 10 are arranged in parallel on the sheets 13 and 14, respectively.
- the via holes 7 for interlayer connection are arranged so that their axes are arranged in the stacking direction of the sheets 13 to 16 and are connected.
- Both ends of the spiral coil L 1 are drawn out and are electrically connected to the conductor pattern 11.
- the lead conductor pattern 11 is exposed on the left and right sides of the sheets 13 and 14, respectively.
- Each of the sheets 13 to 16 is stacked, pressed and then integrally fired to form a laminate 21 having a rectangular parallelepiped shape as shown in FIG.
- Input / output external electrodes 22 and 23 are formed on the left and right end surfaces of the laminate 21.
- the external electrodes 22 and 23 are formed by a method such as coating and baking, sputtering, or vapor deposition.
- a lead conductor pattern 11 is connected to the external electrodes 22 and 23, respectively.
- the surfaces of the external electrodes 22 and 23 are plated with Ni or Sn to improve solderability.
- the spiral coil L 1 whose coil axis is orthogonal to the stacking direction of the laminated body is disposed inside the laminated body 21. ⁇ Then, the left and right ends of the laminated coil 1 are arranged. On the surface, input / output force external electrodes 22, 23 electrically connected to both ends of the spiral coil L1 are provided. Therefore, the laminated coil 1 is a so-called “vertical laminated horizontal coil type” coil component.
- the sheet thickness and the number of ceramic green sheets 16 for the outer layer are Various modified laminated coils 1 were prototyped.

- the occurrence rate of abnormal deposition of plating was measured for each of the prototyped laminated coils 1. The measurement results are shown in the graph of FIG. From the graph, it can be seen that even if the thickness T2 of the outer layer portion is the same, the occurrence rate of abnormal deposition of plating is lower when a plurality of thin ceramic green sheets 16 for the outer layer are laminated (thickness 50). Compare two ceramic green sheets for the outer layer of ⁇ with each other and the case of only one ceramic green sheet for the outer layer with a thickness of 100 ⁇ ). This is because, when the ceramic green sheet 16 for the outer layer is fired, impurities are precipitated on each surface or a part of the material is segregated, so that the insulation resistance of each surface is increased. .
- the insulation resistance between the coil conductor patterns 9, 10 and the surface of the multilayer body 21 is not necessarily proportional to the thickness T2 of the outer layer, but rather the number of the ceramic green sheets 16 for the outer layer.
