Abstract: In an electronic component, capacitor conductors include linear portions parallel or substantially parallel to a lower surface of a laminate, and lead-out portions led out respectively from the linear portions to the lower surface. Outer electrodes are disposed on the lower surface and cover exposed portions where the lead-out portions are exposed at the lower surface, respectively. At least one of the linear portions includes a groove, which is recessed in a direction away from the lower surface, in a region thereof overlapping with the corresponding outer electrode when looking at the electronic component in a plan view from a z-axis direction.

Abstract: A capacitor body includes a capacitance-forming section including an alternately arranged plurality of internal electrodes and plurality of dielectric ceramic layers and outer layer sections disposed on the upper or lower face of the capacitance-forming section (28). The outer layer sections include an outermost layer and a second layer (31) inwardly located therefrom. The second layer has a thermal expansion coefficient greater than that of the outermost layer by 1×10?6/° C. to 3×10?6/° C. The outermost layer has a thickness of 50 to 80 ?m. The second layer has a thickness of 20 to 50 ?m. The arrangement prevents cracks from being formed in a monolithic ceramic capacitor when external electrodes are formed by baking and cooling, and cracks caused by fatigue failure due to low-stress cycles such as heat cycles are prevented from reaching internal electrodes.

Abstract: The “squeal” that occurs when an electric field is applied to a multilayer ceramic capacitor mounted on a substrate is suppressed by providing in an active part contributing to formation of capacitances between internal electrodes facing each other in a capacitor body, low-activity regions positioned near respective end edges of respective external electrodes. A facing area of the internal electrodes in the low-activity regions is less than or equal to one fifth that of the internal electrodes in a normal region having the same volume as that of the low-activity regions. This makes it possible to suppress occurrence of electric-field-induced distortion near the external electrodes bonded to a substrate and reduce the force that causes the substrate to bend.

Abstract: A multilayer capacitor includes a capacitor body in which internal electrodes in a first internal electrode group are overlapped with internal electrodes in a second internal electrode group with dielectric layers sandwiched therebetween. A first external electrode has a first wraparound portion and a second wraparound portion, and a second external electrode has a third wraparound portion and a fourth wraparound portion. The volume proportions of the effective layers in a first area sandwiched between the first wraparound portion and the second wraparound portion and in a third area sandwiched between the third wraparound portion and the fourth wraparound portion are set to at least about 10%. The volume proportions of the effective layers in a second area toward a lower surface in the first area and in a fourth area toward the lower surface in the third area are set to about 15% or less. The external dimensions of the multilayer capacitor 1 are about 1.6±0.1 mm in length by about 0.8±0.
