A laminated ceramic electronic component mounting structure includes a laminated ceramic electronic component including a ceramic body, first and second inner electrodes in the ceramic body including opposed portions including at least portions of which are opposed to each other in a thickness direction of the ceramic body, a first terminal electrode electrically connected to the first inner electrode, and a second terminal electrode electrically connected to the second inner electrode; and a circuit board including first and second electrode lands electrically connected to the first and second terminal electrodes and on which the laminated ceramic electronic component is mounted, wherein widths of the first and second electrode lands are smaller than widths of the first and second inner electrodes at the opposed portions.

Laminated ceramic electronic component mounting structure

A laminated ceramic electronic component includes a ceramic body, first and second inner electrodes within the ceramic body and including opposed portions opposed to each other in the thickness direction of the ceramic body, a first terminal electrode electrically connected to the first inner electrode, and a second terminal electrode electrically connected to the second inner electrode. The widthwise distance between first widthwise edges and second widthwise edges of the first and second terminal electrodes are smaller, in plan view, than widths of the first and second inner electrodes at the opposed portions.

Laminated ceramic electronic component

A monolithic capacitor includes a laminate of ceramic layers, the laminate having first and second surfaces, at least one pair of first and second internal electrodes, first and second external electrodes disposed on the first surface, third and fourth external electrodes disposed on the second surface, a first via conductor that electrically connects the first external electrode to the first internal electrode and to the third external electrode and that contains a metal oxide, and a second via conductor that electrically connects the second external electrode to the second internal electrode and to the fourth external electrode and that contains a metal oxide, wherein, in each of the first and second via conductors, the metal oxide content at an end on the second surface side is higher than the metal oxide content at a center or at an end on the first surface side.
