の製造方法に関するものでおる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inductance element and a method for manufacturing the same, and in particular, an inductance element having a coil pattern that circulates by laminating a magnetic material and a conductor, and a method for manufacturing the same. It's about.

化し巻線を不要とするものである。Inductance elements have long been used as coiled conductive wires, but in order to increase the inductance, magnetic cores such as ferrite cores are also used. However, with the miniaturization of electronic circuits, the demand for miniaturization of electronic components has also increased, and inductance elements are no exception. Although the miniaturization of inductance elements is slower than that of other circuit elements, development is progressing in two broad directions. One is basically the structure of a conventional inductance element (coil), but the size and shape are reduced, and the other is integrated using a printing method or the like, thereby eliminating the need for winding.

この工程を繰り返して形成されるタイプが注目を浴びて
いる。There are various types of inductance elements made by printing methods, but in order to maintain a high inductance value and mechanical strength, an arc-shaped metal pattern for forming a coil is printed on the insulating layer, and one end of the inductance element is printed on the insulating layer. , and print an absolute R layer on it, then connect the ends and form a metal pattern,
The type that is formed by repeating this process is attracting attention.

ダクタンス値を上げることも考えられている。This forms a pattern that circulates in the insulator to form a coil. A desired inductance value can be obtained by appropriately selecting the number of printed layers, and it is also considered that the inductance value can be increased by forming the insulating layer from a magnetic material.
本発明は、上記のような、印刷によって周回導電パター

するものである。The present invention relates to an inductance element in which a circulating conductive pattern is formed by printing, as described above, and a method for manufacturing the same.
印刷によって周回導電パターンを形成するインダクタン

が発生するととＫ ７る。したがって二つの導電ハタ−
７１１０間では磁力線の向きが逆となるので、磁気抵抗
が増すことになる。In an inductance element that forms a circular conductive pattern by printing, the area around the conductive pattern must be an insulator, and in order to increase the inductance value, it is preferably a magnetic material. Therefore, in general, many devices are used in which conductive patterns and insulating magnetic layers are alternately printed. In the inductance element formed in this way, a magnetic layer is interposed between adjacent conductive patterns. Furthermore, since the direction of the current is also the same, as shown in FIG.
When K7 occurs. Therefore, two conductive groups
Since the direction of the magnetic lines of force is reversed between 7110 and 7110, the magnetic resistance increases.
これが、インダクタンス素子のＱ値の劣化をひき起こす
原因となっている。This causes deterioration of the Q value of the inductance element.
本発明は、上記の問題を解決して、磁気抵抗を減少させ
て高いＱ値の得られる□インダクタンス素子を提供する
ことを目的とする。An object of the present invention is to solve the above problems and provide a □ inductance element that can reduce magnetic resistance and obtain a high Q value.
また、単に磁気抵抗を減少させるだけでなく、信頼性が
高く、歩留の良好なインダクタンス素子を得ることを目
的とする。Another objective is not only to simply reduce magnetic resistance, but also to obtain an inductance element with high reliability and good yield.
本発明は、導電パターンの間には透磁率の低い層を介在

Further, this layer with low magnetic permeability is made of the same material as the surrounding magnetic layer, but the magnetic permeability can be changed by changing the composition ratio.
以下、図面に従って本発明の実施例につき説明する。Embodiments of the present invention will be described below with reference to the drawings.

The magnetic layer 15 is made of Ni--Zn ferrite made of the same material as the magnetic material 13, but has a lower Ni content and has lower magnetic permeability than the magnetic material 13.

N-type ferrite powder is mixed with a binder such as methyl cellulose or butyral resin and a solvent to form a paste, and the entire ferrite 17 is printed.

したがって、導電パターンを形成する（印刷する）領域

。Therefore, the region where the conductive pattern is formed (printed) is the groove portion formed by the ferrite 17.

結によって導体１８が収縮しても、十分な厚みを有する
周回導電パターンを形成できる。Next, a paste-like conductor 18 made of a silver-palladium alloy, a binder, and a solvent is printed. It is best to carry out this printing in two stages. First, print to fill the grooves formed by the ferrite 17, and then print the same pattern and the same thickness to fill the grooves formed by the ferrite 17. The thickness should be approximately twice as large (advantageous).In this way, even if the conductor 18 shrinks due to sintering, a circular conductive pattern with sufficient thickness can be formed.

部分を低い透磁率とする。After printing the conductor 18, print the entire ferrite 19 again, but in this case, print twice to increase the thickness (Qo) By doing this, grooves are formed on the conductor 18 by the ferrite 19 again. This ferrite 19 is formed at the same position as the previously formed ferrite 1/, and the same paste is used.In other words, in this case, Ni-Zn ferrite paste is used for both ferrites. It should be shared for printing on 17.19. A paste-like ferrite 20 made by kneading calcined powder of Ni-Zn ferrite with binder and a solvent is placed in a groove formed on the conductor 18 surrounded by ferrite 19.
(10 However, this ferrite is made to have a lower magnetic permeability than the ferrite 17.19 described above. In other words, by changing the content of N1-Zn,
Magnetic permeability can be lowered by reducing the content of . In this way, ferrites made of basically the same material are used, but the magnetic permeability is varied by changing the composition ratio, so that the part between the conductors that will become the electrodes has a low magnetic permeability.

高い磁性体でそれぞれ構成されたコ・イルが得ら八る。The above-described process is repeated 7 to form each circulating conductor pattern by stacking layers while connecting the conductor patterns. A coil/coil is obtained in which the space between the conductors is made of a magnetic material with low magnetic permeability, and the center and the periphery are made of a magnetic material with high magnetic permeability.

とかで８る。According to the present invention, since a magnetic material with low magnetic permeability is formed between the laminated twisted conductors, a magnetic circuit is formed in the center and surrounding ferrites with high magnetic permeability. Therefore, the magnetic flux density of the magnetic circuit formed between the conductors is also reduced, reducing the magnetic resistance of the conductors and improving the Q value.
廿た、同じ磁性体利料で組成比ホを変えただけのフェラ
イトを用いるので、印刷、焼結の工程において収縮率を
均一にしたり剥離を防止できるといった利点もある。Furthermore, since ferrite is used that has the same magnetic material but only a different composition ratio, it has the advantage of making the shrinkage rate uniform and preventing peeling during the printing and sintering processes.
更に、導体、二種類のフェライトを十分な厚みを保たせ
て印刷できるとともに、位置合わせも容易であるという
利点がある。Furthermore, there are advantages in that the conductor and two types of ferrite can be printed while maintaining sufficient thickness, and alignment is also easy.
