Further, since there are three external electrodes, a ground external electrode connection land electrode is required on the circuit board. Furthermore, since the number of terminals is larger than that of a normal bypass capacitor, there is a problem that an extra mounting paste is necessary.

（第１実施例、図１〜図５参照）
本発明に係る積層型セラミック電子部品の第１実施例（ノイズ除去用途の積層型セラミックコンデンサ１）を図１〜図３に示す。この積層型セラミックコンデンサ１は、図１に示すように、第１内部電極３ａ，３ａと浮遊容量分配電極４を表面に設けた複数の誘電体セラミックグリーンシート２Ａ、第２内部電極３ｂを表面に設けた複数の誘電体セラミックグリーンシート２Ｂ、電極を形成していない外層用誘電体セラミックグリーンシート６，７にて構成されている。 (Refer 1st Example and FIGS. 1-5)
A first embodiment of a multilayer ceramic electronic component according to the present invention (multilayer ceramic capacitor 1 for noise removal) is shown in FIGS. As shown in FIG. 1, the multilayer ceramic capacitor 1 has a plurality of dielectric ceramic green sheets 2A provided with first internal electrodes 3a, 3a and a stray capacitance distribution electrode 4 on the surface, and a second internal electrode 3b on the surface. The plurality of dielectric ceramic green sheets 2B provided and the dielectric ceramic green sheets 6 and 7 for outer layers not formed with electrodes are formed.

第１内部電極３ａ，３ａは、誘電体セラミックグリーンシート２Ａの奥側の辺から手前側に向かって所定の間隔で帯状に延在している。浮遊容量分配電極４は、シート２Ａの手前側から奥側に向かって、第１内部電極３ａ，３ａの間に配置されている。第２内部電極３ｂは、幅広であって、誘電体セラミックグリーンシート２Ｂの手前側から奥側に向かって延在しており、第１内部電極３ａ，３ａ及び浮遊容量分配電極４と誘電体セラミックグリーンシート２Ａ又は２Ｂを介して重なっている。   The first internal electrodes 3a, 3a extend in a band shape from the back side of the dielectric ceramic green sheet 2A toward the front side at a predetermined interval. The stray capacitance distribution electrode 4 is disposed between the first internal electrodes 3a and 3a from the front side to the back side of the sheet 2A. The second internal electrode 3b is wide and extends from the front side to the back side of the dielectric ceramic green sheet 2B, and the first internal electrodes 3a and 3a, the stray capacitance distribution electrode 4, and the dielectric ceramic. It overlaps via the green sheet 2A or 2B.

誘電体セラミックグリーンシート２Ａ，２Ｂ，６，７は、誘電体原料粉末を結合剤などとともに混練したものをシート状にしたものが使用される。電極３ａ，３ｂ，４はＡｇを主成分とする導体ペーストを用いて印刷法やフォトリソグラフィ法などにより形成される。   As the dielectric ceramic green sheets 2A, 2B, 6, and 7, a sheet obtained by kneading a dielectric raw material powder together with a binder or the like is used. The electrodes 3a, 3b, and 4 are formed by a printing method, a photolithography method, or the like using a conductive paste mainly composed of Ag.

誘電体セラミックグリーンシート２Ａ，２Ｂ，６，７は積み重ねられた後、一体的に焼成され、図２に示す積層体８とされる。この積層体８において、側面８ａには第２内部電極３ｂの一端部と浮遊容量分配電極４の一端部が露出し、側面８ｂには第１内部電極３ａの一端部が露出している。   Dielectric ceramic green sheets 2A, 2B, 6, and 7 are stacked and then fired integrally to form a laminate 8 shown in FIG. In the multilayer body 8, one end of the second internal electrode 3b and one end of the stray capacitance distribution electrode 4 are exposed on the side surface 8a, and one end of the first internal electrode 3a is exposed on the side surface 8b.

この後、図３に示すように、積層体８の奥側の側面８ｂに、第１内部電極３ａごとに互いに独立しかつ電気的に接続した状態で、第１外部電極１１，１１が設けられる。さらに、積層体８の手前側の側面８ａに、第２内部電極３ｂ及び浮遊容量分配電極４に電気的に接続した状態で、第２外部電極（グランド外部電極）１２が設けられる。図４に、積層体８の内部−外部電極構造を示す。   Thereafter, as shown in FIG. 3, the first external electrodes 11 and 11 are provided on the side surface 8 b on the back side of the multilayer body 8 in a state of being independently and electrically connected to each other for each first internal electrode 3 a. . Further, a second external electrode (ground external electrode) 12 is provided on the front side surface 8 a of the multilayer body 8 in a state of being electrically connected to the second internal electrode 3 b and the stray capacitance distribution electrode 4. FIG. 4 shows the internal-external electrode structure of the laminate 8.

こうして得られた積層型セラミックコンデンサ１は、第１内部電極３ａと第２内部電極３ｂの間に静電容量が形成され、コンデンサアレイを構成する。さらに、第１内部電極３ａと浮遊容量分配電極４の間に浮遊容量Ｃｓが形成される。そして、端子数が少ないので実装用ペーストが少なくて済む。   The multilayer ceramic capacitor 1 obtained in this way has a capacitance formed between the first internal electrode 3a and the second internal electrode 3b, and constitutes a capacitor array. Further, a stray capacitance Cs is formed between the first internal electrode 3 a and the stray capacitance distribution electrode 4. And since the number of terminals is small, less mounting paste is required.

さらに、図４に示すように、積層型セラミックコンデンサ１の第１外部電極１１，１１相互間にコイルＬを電気的に接続することにより、この積層型セラミックコンデンサ１をバイパスコンデンサとして使用する場合、回路基板側でパターン変更することなく、優れたノイズ特性が得られる。   Furthermore, as shown in FIG. 4, when the multilayer ceramic capacitor 1 is used as a bypass capacitor by electrically connecting a coil L between the first external electrodes 11 and 11 of the multilayer ceramic capacitor 1, Excellent noise characteristics can be obtained without changing the pattern on the circuit board side.

即ち、この場合、積層型セラミックコンデンサ１は、コイルＬと共に図５（Ａ）に示す等価回路のＬＣノイズフィルタを構成する。この等価回路は図５（Ｂ）に示す回路と等価であり、浮遊容量Ｃｓは分配される。この結果、積層型セラミックコンデンサ１とコイルＬはπ型のＬＣノイズフィルタを構成することとなり、見かけ上の浮遊容量が減り、効率よくノイズを除去することができる。   That is, in this case, the multilayer ceramic capacitor 1 constitutes the LC noise filter of the equivalent circuit shown in FIG. This equivalent circuit is equivalent to the circuit shown in FIG. 5B, and the stray capacitance Cs is distributed. As a result, the multilayer ceramic capacitor 1 and the coil L constitute a π-type LC noise filter, the apparent stray capacitance is reduced, and noise can be efficiently removed.

A second embodiment (multilayer ceramic capacitor 20 for noise removal) of the multilayer ceramic electronic component according to the present invention is shown in FIGS. As shown in FIG. 6, the multilayer ceramic capacitor 20 includes a plurality of dielectric ceramic green sheets 22A having a first inner electrodes 23a, 23a, a stray capacitance distribution electrode 24, and dummy electrodes 25a, 25b provided on the surface, a second A plurality of dielectric ceramic green sheets 22B provided with internal electrodes 23b and dummy electrodes 25c on the surface, and outer-layer dielectric ceramic green sheets 26, 27 on which no electrodes are formed.

The stray capacitance distribution electrode 24 is disposed between the first internal electrodes 23a and 23a from the left side of the sheet 22A toward the right. The dummy electrode 25a is disposed on the left side of the sheet 22A, and the dummy electrode 25b is disposed on the right side of the sheet 22A so as to face the other end of the stray capacitance distribution electrode 24.

The first internal electrodes 23a and 23a, the stray capacitance distribution electrode 24, and the dielectric ceramic green sheet It overlaps via 22A or 22B. The dummy electrode 25c is disposed on the right side of the sheet 22B.

誘電体セラミックグリーンシート２２Ａ，２２Ｂ，２６，２７の材料、電極２３ａ，２３ｂ，２４，２５ａ，２５ｂ，２５ｃの材料やその形成方法は、前記第１実施例と同様である。   The material of the dielectric ceramic green sheets 22A, 22B, 26, and 27, the material of the electrodes 23a, 23b, 24, 25a, 25b, and 25c and the formation method thereof are the same as in the first embodiment.

誘電体セラミックグリーンシート２２Ａ，２２Ｂ，２６，２７は積み重ねられた後、一体的に焼成され、図７に示す積層体２８とされる。この積層体２８において、側面２８ａには第２内部電極２３ｂの一端部と浮遊容量分配電極２４の一端部とダミー電極２５ａの一端部が露出している。また、側面２８ｂには第１内部電極２３ａの一端部とダミー電極２５ｂ，２５ｃの一端部が露出している。   Dielectric ceramic green sheets 22A, 22B, 26, and 27 are stacked and then fired integrally to form a laminated body 28 shown in FIG. In the laminated body 28, one end of the second internal electrode 23b, one end of the stray capacitance distribution electrode 24, and one end of the dummy electrode 25a are exposed on the side surface 28a. Further, one end of the first internal electrode 23a and one end of the dummy electrodes 25b and 25c are exposed on the side surface 28b.

この後、図８に示すように、積層体２８の側面２８ｂに、第１内部電極２３ａごとに互いに独立しかつ電気的に接続した状態で、第１外部電極３１，３１が設けられる。ダミー電極２５ｃは第１外部電極３１と電気的に接続され、ダミー電極２５ｂは第１外部電極３１と接続されることはなく、浮き電極となっている。さらに、積層体２８の側面２８ａに、第２内部電極２３ｂ及び浮遊容量分配電極２４に電気的に接続した状態で、第２外部電極（グランド外部電極）３２が設けられる。ダミー電極２５ａは第２外部電極３２と電気的に接続される。   Thereafter, as shown in FIG. 8, the first external electrodes 31, 31 are provided on the side surface 28 b of the multilayer body 28 in a state of being independently and electrically connected to each other for each first internal electrode 23 a. The dummy electrode 25c is electrically connected to the first external electrode 31, and the dummy electrode 25b is not connected to the first external electrode 31, but is a floating electrode. Furthermore, a second external electrode (ground external electrode) 32 is provided on the side surface 28 a of the multilayer body 28 in a state of being electrically connected to the second internal electrode 23 b and the stray capacitance distribution electrode 24. The dummy electrode 25a is electrically connected to the second external electrode 32.

こうして得られた積層型セラミックコンデンサ２０は、前記第１実施例と同様に、第１内部電極２３ａと第２内部電極２３ｂの間に静電容量が形成され、コンデンサアレイを構成する。さらに、第１内部電極２３ａと浮遊容量分配電極２４の間に浮遊容量（第１実施例の図５に示すＣｓと等価である）が形成される。   In the multilayer ceramic capacitor 20 thus obtained, a capacitance is formed between the first internal electrode 23a and the second internal electrode 23b, as in the first embodiment, and constitutes a capacitor array. Further, a stray capacitance (equivalent to Cs shown in FIG. 5 of the first embodiment) is formed between the first internal electrode 23a and the stray capacitance distribution electrode 24.

そして、積層型セラミックコンデンサ２０の第１外部電極３１，３１相互間にコイルを電気的に接続することにより、この積層型セラミックコンデンサ２０をバイパスコンデンサとして使用できる。コイルを接続した積層型セラミックコンデンサ２０は、基本的には図５（Ａ），（Ｂ）に示す等価回路と同様のＬＣノイズフィルタを構成する。従って、本第２実施例の作用効果は前記第１実施例と基本的に同じである。さらに、本第２実施例では、ダミー電極２５ａ，２５ｂ，２５ｃを設けることによって、積層体２８の歪みが少なくなるとともに、積層によって累積した内部電極２３ａ，２３ｂの厚みによる段差を解消し、デラミネーションやクラックの発生が防止される。   The multilayer ceramic capacitor 20 can be used as a bypass capacitor by electrically connecting a coil between the first external electrodes 31 of the multilayer ceramic capacitor 20. The multilayer ceramic capacitor 20 to which the coil is connected basically constitutes an LC noise filter similar to the equivalent circuit shown in FIGS. Accordingly, the operational effects of the second embodiment are basically the same as those of the first embodiment. Furthermore, in the second embodiment, by providing the dummy electrodes 25a, 25b, and 25c, the distortion of the laminated body 28 is reduced, and the step due to the thickness of the internal electrodes 23a and 23b accumulated by the lamination is eliminated, and delamination is performed. And cracks are prevented.
