Conductive paste
Provided is a conductive paste for an internal electrode, which is capable of maintaining a relatively high coverage rate even if the internal electrode of a laminated ceramic capacitor is thinned. A conductive paste for forming internal electrodes (4, 5) of a multilayer ceramic capacitor (1) manufactured through a firing step, the conductive paste comprising a conductive metal powder, a ceramic powder, an organic solvent, and an organic binder, the conductive metal powder comprising copper, at least a portion of the ceramic powder is a powder containing an ABO3-type oxide having a specific ionic radius in which the ratio of the ionic radius of an A-site element in ABO3 at the 6-coordinate to the ionic radius of copper at the 6-coordinate is 0.96-1.04.
本发明提供一种即使层叠陶瓷电容器的内部电极被薄层化也能够将覆盖率维持得比较高的内部电极用的导电性膏。一种用于形成经过烧成工序而制造的层叠陶瓷电容器(1)的内部电极(4、5)的导电性膏，包含导电性金属粉末、陶瓷粉末、有机溶剂以及有机粘合剂，导电性金属粉末包含铜，陶瓷粉末的至少一部分是包含ABO3中的A位的元素的6配位下的离子半径相对于铜的6配位下的离子半径的比率处于0.96以上且1.04以下的、特定离子半径的ABO3型的氧化物的粉末。
