Abstract:
1. A monolithic ceramic capacitor comprising: a capacitor body including a plurality of laminated ceramic layers and having a first principal surface, a second principal surface facing the first principal surface, and side surfaces connecting the first principal surface and the second principal surface; a plurality of first external terminal electrodes each of which is connected to a first potential, the first external terminal electrodes being provided on the side surfaces of the capacitor body; a plurality of second external terminal electrodes each of which is connected to a second potential, the second external terminal electrodes being provided on the side surfaces of the capacitor body; a first internal electrode provided inside the capacitor body and electrically connected to at least one of the plurality of first external terminal electrodes; a second internal electrode provided inside the capacitor body and electrically connected to at least one of the plurality of second external terminal electrodes; a third internal electrode provided inside the capacitor body and electrically connected to at least one of the plurality of first external terminal electrodes; a fourth internal electrode provided inside the capacitor body and electrically connected to at least one of the plurality of second external terminal electrodes; at least one first capacitor provided inside the capacitor body, and having a capacitance that is provided by arranging the first internal electrode and the second internal electrode with a specific one of the ceramic layers therebetween; at least one second capacitor provided inside the capacitor body so as to be arranged adjacent to the at least one first capacitor in a plan view of the ceramic layers, the at least one second capacitor having a capacitance that is provided by arranging the third internal electrode and the fourth internal electrode with a specific one of the ceramic layers therebetween; and at least one first same-polarity-connection conductor provided on one of the plurality of laminated ceramic layers inside the capacitor body, the at least one first same-polarity-connection conductor extending over at least two capacitors selected from the at least one first capacitor and the at least one second capacitor and being electrically connected to at least two of the plurality of first external terminal electrodes; wherein the side surfaces of the capacitor body include a first side surface and a second side surface facing the first side surface; the at least one first same-polarity-connection conductor includes a singular main body portion and a plurality of leading portions extending from the singular main body portion; at least two of the plurality of leading portions extend from the singular main body portion to each of the first and second side surfaces; a shape of each of the at least one same-polarity-connection conductor is different from each of a shape of the first, second, third, and fourth internal electrodes; and each of the plurality of first external terminal electrodes and each of the plurality of second external electrodes is connected to at least one of the first, second, third, and fourth internal electrodes.
