A composite substance for forming a conductive paste, comprises a solvent being compatible with an organic component included in the conductive paste, and metal particles wetted by the solvent. The conductive paste comprises an organic binder, the composite substance and an organic solvent mixed with the organic binder and the composite substance. The method for manufacturing the composite substance comprises the step of adding the solvent to undried metal particles having been washed with water, the solvent being compatible with the organic binder included in the conductive paste and incompatible with water so that the water is replaced by the solvent. The method for manufacturing the conductive paste comprises the step of mixing an organic binder and an organic solvent with the composite substance.
It is an object of the present invention to provide a method for manufacturing a multilayered unit for a multi-layered ceramic electronic component which can reliably prevent short circuit failure from occurring 5 in a multi-layered ceramic electronic component. According to the present invention, a multi-layered unit for a multi-layered ceramic electronic component is fabricated by printing a conductive paste containing a butyral system resin as a binder and at least one solvent selected from a group consisting of dihydroterpinyl oxyethanol, terpinyl oxyethanol, d-dihydrocarveol, I-citronellol, I-perillylalcohol and acetoxy-methoxyethoxy-cyclohexanol acetate as a solvent on a ceramic green sheet containing an acrylic system resin as a binder in a predetermined pattern, thereby forming an electrode layer.
It is an object of the present invention to provide a dielectric paste for a spacer layer of a multi-layered ceramic electronic component which 5 does not dissolve a binder contained in a layer adjacent to the spacer layer of the multi-layered ceramic electronic component and can reliably prevent defects from being generated in a multi-layered ceramic electronic component. A dielectric paste for forming a spacer layer according to the 10 present invention contains a butyral system resin as a binder and at least one solvent selected from the group consisting of dihydroterpinyl oxyethanol, terpinyl oxyethanol, d-dihydrocarveol, I-citronellol, I-perillylalcohol and acetoxy-methoxyethoxy-cyclohexanol acetate as a solvent.
It is an object of the present invention to provide a method for manufacturing a multi-layered unit for a multi-layered ceramic electronic component which can reliably prevent short circuit failure from occurring in a multi-layered ceramic electronic component and form an electrode layer in a desired manner.A method for manufacturing a multi-layered ceramic electronic component includes a step of printing a conductive paste containing a binder containing ethyl cellulose having a weight average molecular weight of MW.sub.L and ethyl cellulose having a weight average molecular weight of MW.sub.H at a weight ratio of X:(1-X), where MW.sub.L, MW.sub.H and X are selected so that X*MW.sub.L+(1-X)*MW.sub.H falls within a range of 145,000 to 215,000 and at least one solvent selected from the group consisting of isobornyl acetate, dihydroterpinyl methyl ether, dihydroterpinyl oxyethanol, terpinyl methyl ether, terpinyl oxyethanol, d-dihydrocarveol, I-menthyl acetate, I-citronellol, I-perillylalcohol and acetoxy-methoxyethoxy-cyclohexanol acetate on a ceramic green sheet containing an acrylic system resin as a binder in a predetermined pattern, thereby forming an electrode layer.
