    摘要: A monolithic ceramic capacitor includes a sintered ceramic compact having a core-shell structure, a plurality of internal electrodes arranged in and separated by the ceramic sintered compact so as to overlap in the thickness direction, and a plurality of external electrodes formed on the outermost faces of the ceramic sintered compact. In the core-shell structure, cores are composed of a particulate dielectric ceramic, and shells are formed on the cores and are composed of a material having a dielectric constant lower than that of the dielectric ceramic. The area ratio of the cores to the shells lies in a range of 7:3 to 3:7 in a cross-section of the sintered ceramic compact in an arbitrary direction. The core-shell structure can achieve further miniaturization and higher capacitance of the monolithic ceramic capacitor, in addition to superior temperature characteristics.

    摘要: A highly reliable monolithic ceramic capacitor which has no structural defect, e.g. peeling, and which is not susceptible to water from the outside and a method for manufacturing the same are provided. A lead portion of an internal electrode is configured to have a shape provided with a taper-shaped portion in which the width gradually decreases with increasing proximity to the end surface of a ceramic element, and the shape of the end portion opposite to the lead portion of the internal electrode is adjusted to be substantially rectangular. Regarding a pair of internal electrodes facing each other with the ceramic layer therebetween, the internal electrodes are laminated while the positions thereof are displaced with respect to each other in order that a corner portion in the substantially rectangular portion of one internal electrode are located in the vicinity of, but outside the taper-shaped portion of the other internal electrode.
