That is, in the second arrangement structure, the number of stacked layers of the second ESR control unit 20 is changed as compared with the first arrangement structure. As in the first arrangement structure, a substantially intermediate layer in the stacking direction of one second ESR control unit 20 arranged in the uppermost layer and one first ESR control unit 10 arranged in the lowermost layer is formed. The remaining one layer of the second ESR control unit 20 is arranged. In addition, the electrostatic capacitance part 30 is arrange | positioned at the upper layer of the 2nd ESR control part 20 located in an intermediate | middle layer, for example, and four layers are arrange | positioned in the lower layer.

  In the case of the second arrangement structure, a detailed description of the current path is omitted, but the multilayer capacitor 1 routes the current path in the entire vertical direction of the first external connection conductors 5 and 6 on the plus side and the minus side. In addition to the first current path passing through the second ESR control unit 20 of the uppermost layer, the current path is routed from the lower end in the vertical direction of the first outer connecting conductors 5 and 6 to the vicinity of the intermediate layer to The second current path via the second ESR control unit 20 is also provided. Since the resistors R by the first and second current paths are connected in parallel, the second arrangement structure makes fine adjustments such as slightly lowering the resistance R compared to the first arrangement structure. As a result, the ESR value of the multilayer capacitor 1 can be finely adjusted to be slightly lower than that of the first arrangement structure.

  Further, in the third arrangement structure shown in FIG. 5, in the multilayer capacitor 1 in which the element body 2 has a ten-layer structure as a whole, the first ESR control unit 10 is further formed in the second arrangement structure as in the second arrangement structure. The ESR control unit 20 includes two layers, and the capacitance unit 30 includes the remaining seven layers. On the other hand, in the third arrangement structure, unlike the second arrangement structure, the stacking position is set so that the second ESR control unit 20 located in the intermediate layer is higher than the intermediate layer in the stacking direction. It has changed. Note that, for example, two layers of the electrostatic capacity unit 30 are disposed on the upper layer of the second ESR control unit 20 that has been changed to be an upper layer than the intermediate layer, and five layers are disposed on the lower layer thereof.

  In the case of the third arrangement structure, a detailed description of the current path is omitted, but the second current path is slightly longer, so that the second of the resistors R connected in parallel as in the second arrangement structure. The value of the resistance R by the second current path can be made higher than that of the second arrangement structure, and the ESR value of the multilayer capacitor 1 is slightly higher than that of the second arrangement structure. Can be adjusted. In the second and third arrangement structures, the number of layers of the second ESR control unit 20 compared to the case of the first arrangement structure can be changed by further changing the lamination position of the second ESR control unit 20 in the uppermost layer. Of course, the ESR may be finely adjusted by changing both the stacking position and the stacking position.

  As described above, in the multilayer capacitor 1 and the method for adjusting the equivalent series resistance of the multilayer capacitor 1, the multilayer capacitor 1 includes the second ESR control unit 20 connected to the first and second external connection conductors 5 to 8. The equivalent series resistance of the multilayer capacitor 1 is changed by changing at least one of the number of laminations and the lamination position of the second ESR control unit 20 to any of the first arrangement structure to the third arrangement structure described above, for example. Is adjusted to a desired value. Elements such as the number of laminations and the lamination position of the second ESR control unit 20 are elements that are relatively easy to adjust in the lamination process of the multilayer capacitor 1, and the equivalent series resistance is adjusted by changing this. The equivalent series resistance of the multilayer capacitor 1 can be finely adjusted. In the arrangement structure described above, the first arrangement structure to the third arrangement structure are exemplarily shown, but the structure for adjusting the equivalent series resistance is not limited to these.

  Then, each part which comprises a laminated body, and the internal electrode contained in each part are demonstrated. The first ESR control unit 210 includes internal electrodes 211 and 216 as shown in FIG. The internal electrode 211 includes a main electrode part 212 and extraction electrode parts 213 and 214 and connects the terminal electrode 3 and the first external connection conductor 5. The internal electrode 216 includes a main electrode portion 217 and extraction electrode portions 218 and 219, and connects the terminal electrode 4 and the first external connection conductor 6.

Not only the internal electrode 226 of the second ESR control unit 220 but also the internal electrode 246 of the third ESR control unit 240 are connected to the second external connection conductor 8. When the multilayer capacitor 201 is mounted on the circuit board or the like, current flows through the internal electrodes 231 and 236 facing each other in the capacitance unit 230, and as a result, a predetermined capacitance is generated between the electrodes 231 and 236. Occur.

  As described above, the multilayer capacitor 201 according to the present embodiment also includes the second ESR control unit 220 as in the second embodiment, and at least one of the number of layers and the position of the second ESR control unit 220 is stacked. By changing the ESR, the ESR of the multilayer capacitor 201 can be adjusted to a desired value.

  In the multilayer capacitor 201, the terminal electrode is composed of terminal electrodes 3, 53, 4, 54 connected to the same polarity, and the internal electrodes 211, 216 of the first ESR controller 210 are the terminal electrodes 3, 4.

  In this case, the multilayer capacitor 201 includes a third ESR control unit 240 in addition to the current path connecting the terminal electrodes 3 and 4 and the capacitance unit 230 via the first and second ESR control units 210 and 220. Thus, another current path that connects the terminal electrodes 53 and 54 and the capacitance unit 230 is provided in parallel. As described above, by providing two types of current paths in which the multilayer capacitor 201 is arranged in parallel, as in the case where the second ESR control unit is increased in the first embodiment, further fine adjustment of the equivalent series resistance is performed. be able to. In other words, since these two current paths can have different lengths, the current connecting the terminal electrodes 3 and 4 and the capacitance unit 230 via the first and second ESR control units 210 and 220. The resistor R1 in the path and the resistor R2 in the current path that connects the terminal electrodes 53 and 54 and the capacitance unit 230 via the third ESR control unit 240 are different from each other and arranged in parallel. Thus, the ESR can be adjusted.

  Moreover, in the present embodiment, unlike the first embodiment, a different current path is provided by the third ESR control unit 240 having a different internal electrode pattern from the first and second ESR control units 210 and 220. Yes. For this reason, the length of the current path by the third ESR control unit 240 can be set regardless of the first or second ESR control unit 210, 220, and the value of the resistor R2 can be set more finely or freely. As a result, the ESR value in the multilayer capacitor 201 can be further finely adjusted.

  In the above-described embodiment, the internal electrodes 211 and 216 of the first ESR control unit 210 and the internal electrodes 241 and 246 of the third ESR control unit 240 are formed in the same layer in the stacking direction of the dielectric layer 2g. As shown in FIGS. 19A and 19B, the internal electrodes 211 and 216 of the first ESR control unit 210 and the internal electrodes 241 and 246 of the third ESR control unit 240 May be formed in different layers in the laminating direction of the dielectric layer 2g. In this case, compared with the case where it is formed in the same layer, the variation variations such as the positions of the first, second and third ESR control units 210, 220, 240 and the capacitance unit 230 can be increased. Fine adjustment of the ESR 201 can be performed more easily.

  For example, the arrangement structure in the element body 2 of the first, second and third ESR control units 210, 220, 240 and the capacitance unit 230 is shown in FIG. In the arrangement structure of FIG. 20, the first ESR control unit 210, the second ESR control unit 220, and the capacitance unit 230 from the lower layer (main surface 2b) side to the upper layer (main surface 2a) side in the stacking direction. And the third ESR control unit 240 are arranged in this order. The arrow on the left side of the drawing schematically shows the flow of the current I on the positive electrode side, and the arrow on the right side of the drawing schematically shows the flow of the current I on the negative electrode side.

  Then, for example, as shown in FIG. 21A, the arrangement structure of the multilayer capacitor 201 having such an arrangement structure is changed from the lower layer side to the upper layer side in the lamination direction. It changes so that it may arrange in order of capacity part 230, the 3rd ESR control part 240, and the 2nd ESR control part 220. The arrow on the right side of the figure schematically shows the flow of the current I through the first and second ESR control units 210 and 220, and the arrow on the left side of the figure passes through the third ESR control unit 240. The flow of the current I is schematically shown (only the positive electrode side is shown). In such a case, as is apparent from FIG. 21A, the current path connecting the first and second ESR control units 210 and 220 becomes longer, and therefore the first and second ESR control units 210 and 220 are connected. It is possible to make an adjustment such that the resistance R1 in the current path via is increased as compared with the arrangement structure of FIG.

  Further, for example, as shown in FIG. 21B, the arrangement structure of the multilayer capacitor 201 having the arrangement structure shown in FIG. 20 is changed from the lower layer side to the upper layer side in the lamination direction. The second ESR control unit 220, the first ESR control unit 210, and the third ESR control unit 240 are arranged in this order. The arrow on the right side of the figure schematically shows the flow of the current I through the first and second ESR control units 210 and 220, and the arrow on the left side of the figure passes through the third ESR control unit 240. The flow of the current I is schematically shown (only the positive electrode side is shown). In such a case, as is clear from FIG. 21B, the current path connecting the third ESR control unit 240 becomes longer, so that the resistance R2 in the current path via the third ESR control unit 240 is It is possible to perform an adjustment such as an increase compared to the case of 20 arrangement structures.

  Further, for example, as shown in FIG. 21C, the arrangement structure of the multilayer capacitor 201 having the arrangement structure shown in FIG. 20 is changed from the lower layer side to the upper layer side in the lamination direction. The capacitance unit 230, the second ESR control unit 220, and the third ESR control unit 240 are arranged in this order. The arrow on the right side of the figure schematically shows the flow of the current I through the first and second ESR control units 210 and 220, and the arrow on the left side of the figure passes through the third ESR control unit 240. The flow of the current I is schematically shown (only the positive electrode side is shown). In such a case, as is clear from FIG. 21C, both the current path connecting the first and second ESR control units 210 and 220 and the current path connecting the third ESR control unit 240 are to some extent. Therefore, since the length is longer, it is possible to adjust the both resistances R1 and R2 to some extent as compared with the arrangement structure of FIG.
