Abstract:
1. A monolithic capacitor comprising: a laminate including a plurality of ceramic layers, the laminate having a first surface and a second surface opposing the first surface; at least one pair of first and second internal electrodes opposed to each other with one of the ceramic layers disposed therebetween; a first external electrode and a second external electrode disposed on the first surface; a third external electrode and a fourth external electrode disposed on the second surface; a first via conductor arranged to electrically connect the first external electrode to the first internal electrode and to the third external electrode, that extends between the first surface and the second surface, and that is made of a material including a metal oxide, wherein the metal oxide content at an end on the second surface side of the first via conductor is higher than at least one of the metal oxide content at a center and the metal oxide content at an end on the first surface side of the first via conductor; and a second via conductor arranged to electrically connect the second external electrode to the second internal electrode and to the fourth external electrode, that extends between the first surface and the second surface, and that is made of a material containing a metal oxide, wherein the metal oxide content at an end on the second surface side of the second via conductor is higher than at least one of the metal oxide content at a center and the metal oxide content at an end on the first surface side of the second via conductor.
