置ずれが発生し、内部電極層の精度の低下が生じる。In order to form a laminated ceramic capacitor of desired accuracy with a high yield, it is necessary to form the internal electrode layers with high accuracy. In order to form the internal electrode layers with high accuracy, it is necessary to increase the accuracy of printing the conductive paste and the accuracy of stacking the green sheets having the conductive paste coating layer. In order to increase the accuracy of stacking, it is necessary to improve the mechanical accuracy of stacking and also improve the adhesion between the green sheets. If the adhesion between the green sheets is poor,
When the laminated body is removed from the jig, a part or the whole of the green sheet is peeled off due to static electricity or air entrapment phenomenon, which causes a positional deviation, which lowers the accuracy of the internal electrode layers.

る。In order to improve the adhesion of the green sheet, it is conceivable to increase the amount of the organic binder in the green sheet or increase the amount of the plasticizer. However, if the former method is adopted, since the proportion of the organic binder in the green sheet becomes too large, it becomes difficult to remove it by thermal decomposition, that is, it is difficult to perform good debinding, and the sintering state is poor. Become. Further, when the latter method is adopted, the deformation of the green sheet at room temperature becomes large, and it becomes difficult to stack the green sheets with high accuracy.

ーが良好に進行し、焼結性を低下させない。The rosin-containing conductive coating layer of the present invention has an adhesive force, and adheres to a porcelain green sheet (green sheet) facing it when laminated. Therefore, peeling and displacement of the green sheet are unlikely to occur during stacking and thereafter. 50-90% by weight of an organic binder and 10-
A mixture of 50% by weight rosin will provide adequate adhesion. When the organic binder is a combination of ethyl cellulose and rosin as described in claim 3, the rosin compensates for the insufficient adhesion of ethyl cellulose. That is, a film obtained by printing a conductive paste composed of metal powder and ethyl cellulose on a green sheet and drying it does not substantially have adhesiveness, and the laminate is adhered only in the green sheet area. The adhesion between them is low. On the other hand, when rosin is mixed, the adhesive force of the conductive coating layer increases, and the entire area between the green sheets functions as an adhesive area. Rosin is ethyl cellulose
Like other synthetic resins used as a binder and an organic binder, it is thermally decomposed from around 200 ° C., so that the binder removal proceeds well and the sinterability does not decrease.

Next, palladium metal powder was added to one half of this organic binder liquid and stirred, and then the other half was added and stirred to obtain a conductive paste. The viscosity and thixo ratio of this conductive paste were almost the same as those of the conventional paste.

トの位置ずれが少なくなるためである。According to the present embodiment, a laminated ceramic capacitor having a target range of capacitance can be obtained with a high yield. That is, it was possible to obtain a yield higher than the production yield of the laminated ceramic capacitor when the conventional organic binder containing no rosin was used. The reason for the high yield is that the inclusion of rosin enhances the adhesive force between the dried electrode coating layer 2 and the green sheet that faces the electrode coating layer 2 at the time of stacking, and the positional deviation of the green sheet at the time of stacking occurs. This is because there will be less.

The adhesive strength of was measured and found to be 18 grams. As is clear from the comparison between the comparative example and the example, the adhesive force between the green sheets can be significantly improved by using the organic binder containing the rosin of this example.
