摘要： In an embodiment, in a multilayer ceramic capacitor 10, a first insulative layer 13-1 having parts A1, A2 covered by the first part 12b of each external electrode 12 is provided on one third-direction face, while a second insulative layer 13-2 having parts A3, A4 covered by the second part 12c of each external electrode 12 is provided on the other third-direction face, of the capacitor body 11 of the multilayer ceramic capacitor 10. The multilayer ceramic electronic component can prevent moisture intrusion into the component body as much as possible, even when the multilayer ceramic electronic component is made thin.

摘要： In an embodiment, a multilayer ceramic capacitor 10 has supplementary dielectric layers 11d covering the spaces between two first base conductor films 11c on both height-direction faces of a capacitive element 11′, respectively, in such a way that clearances CL are left between the first base conductor films 11c and the supplementary dielectric layers 11d in the length direction. External electrodes 12, 13 each have a second base conductor film 12a, 13a and a surface conductor film 12b, 13b, and the wraparound locations 12b1, 13b1 of each surface conductor film 12b, 13b have insertion parts 12b2, 13b2 that fill in the clearances CL. The multilayer ceramic capacitor can mitigate deterioration in moisture resistance.

摘要： In an embodiment, a multilayer ceramic capacitor 10 has supplementary dielectric layers 11d, each having a first cover part 11d1 that covers the space between two first base conductor films 11c on each of both height-direction faces, and second cover parts 11d2 that connect to the first cover part 11d1 and also cover parts of the first base conductor films 11c, respectively, in the length direction. External electrodes 12, 13 each have a second base conductor film 12a, 13a attached to a one length-direction face and to one length-direction edges of two first base conductor films 11c on the respective height-direction faces, and a surface conductor film 12b, 13b attached continuously to the surface of the second base conductor film 12a, 13a and also to the parts of the surfaces of the two first base conductor films 11c not covered by the second cover parts 11d2.
