摘要： In a multilayer ceramic electronic component, when a region of a ceramic body in layers where neither of a first internal electrode and a second internal electrode is provided as viewed in a direction in which a plurality of ceramic layers are stacked on one another is defined as a non-effective layer region, a dummy lead-through conductor is arranged in the non-effective layer region so as to lead to at least two locations on portions of superficies of the ceramic body and be electrically connected to a second external electrode. When a conductive medium is brought into contact with one of a plurality of exposed edges of the dummy lead-through conductor, a current is also applied to the other exposed edges.

摘要： A laminated ceramic electronic component includes curved surface portions provided in an outer surface of a ceramic element assembly, and internal conductors provided within the ceramic element assembly that are exposed in the curved surface portions and principal surfaces to define starting points for plating deposition. A base layer, in an external conductor, which is defined by a plating film is arranged so as to directly cover the exposed portions of the internal conductors.

摘要： 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.
摘要翻译： 在单片陶瓷电子部件中，由于外层部分相邻的外层虚设导体之间的间隔为d1，内层部分相邻的第一内电极与第二内电极的间隔为d2 ，1.7d2@d1满足。 通过在该条件下减小外层部分中的外层虚设导体的密度，通过外层虚设导体按压内电极在烧制前的加压步骤中被释放。 结果，可以防止内部电极之间的距离局部缩短。 因此，可以有效地降低并防止单片陶瓷电子部件的可靠性的劣化，例如BDV的降低。

摘要： An electronic component includes a coil whose inductance changes in accordance with the magnitude of a current and in which abrupt reduction in the inductance due to magnetic saturation is suppressed. A stack formed by a plurality of stacked first magnetic layers includes a coil formed by coil electrodes connected to one another in the stack. A first nonmagnetic layer is arranged in such a manner as to cut across the coil. When viewed in a stacking direction, a second nonmagnetic layer is formed in a region outside of a region in which the coil is formed. The structure of the second nonmagnetic layer on the upper side of the first nonmagnetic layer in the stacking direction is different from a structure of the second magnetic layer on the lower side of the first nonmagnetic layer in the stacking direction.
