  • Patent number: 8797708
    Abstract: Two or more outer-layer dummy conductors are successively arranged at predetermined intervals in the height direction, thereby forming a plurality of outer-layer dummy groups. Given that an interval between the adjacent outer-layer dummy conductors within each of the outer-layer dummy groups is d and an interval between the adjacent outer-layer dummy groups is g, g is greater than d. On that condition, the outer-layer dummy groups can be positioned satisfactorily apart away from each other, while plating deposition points are ensured. As a result, pressing of inner electrodes through the outer-layer dummy conductors can be relieved, whereby the distance between the inner electrodes can be prevented from being locally shortened and a reduction of BDV can be prevented.

  • Patent number: 8654504
    Abstract: In a monolithic ceramic electronic component, given that an interval between outer-layer dummy conductors adjacent to each other in an outer layer portion is d1, and that an interval between first and second inner electrodes adjacent to each other in an inner layer portion is d2, 1.7d2?d1 is satisfied. By reducing a density of the outer-layer dummy conductors in the outer layer portion on that condition, pressing of the inner electrodes through the outer-layer dummy conductors is relieved in a pressing step before firing. As a result, a distance between the inner electrodes can be prevented from being locally shortened. It is hence possible to effectively reduce and prevent degradation of reliability of the monolithic ceramic electronic component, e.g., a reduction of BDV.
