摘要： A multilayer capacitor includes a laminate of ceramic layers, and a capacitor unit provided in the laminate. In the multilayer capacitor, the relationships P≧Ra and P≧W are established, wherein P represents the average projection height of first and second via conductors from the upper surface, Ra represents the surface roughness of the upper surface, and W represents an amount of curvature of the laminate. Further, the projecting portions of the first and second via conductors projecting from the upper surface are buried in first and second external electrodes, respectively.

摘要： In a monolithic ceramic capacitor, the size of end surfaces of a capacitor body in a two-dimensional surface in which ceramic layers extend is greater than the size of side surfaces in the two-dimensional surface in which the ceramic layers extend. External terminal electrodes include a resistive component. In each of first to fourth internal electrodes, a width-direction size of a lead-out portion is less than a width-direction size of a capacitance portion. The lead-out portions of the first and third internal electrodes and the lead-out portions of the second and fourth internal electrodes are arranged so as to partially overlap each other or not to overlap each other.

摘要： In an LW-reverse-type monolithic ceramic capacitor including external terminal electrodes each including a resistance component, internal electrodes include nickel or a nickel alloy, and the external terminal electrodes each include a first layer, a second layer provided on the first layer, and a third layer provided on the second layer. The first layer has a wrap-around portion extending from an end surface to principal surfaces and side surfaces of a capacitor main body, and contains a glass component and a compound oxide that reacts with Ni or the Ni alloy. The second layer covers the first layer such that the edge of the wrap-around portion of the first layer remains exposed, and contains a metal. The third layer covers the edge of the wrap-around portion of the first layer and the second layer, and is formed by plating.
