Abstract:
1. A multilayer capacitor comprising: a rectangular parallelepiped capacitor body having oblong first and second main faces opposing each other, first and second side faces extending in a longer side direction of the first and second main faces, connecting the first and second main faces to each other and opposing each other, and third and fourth side faces extending in a shorter side direction of the first and second main faces, connecting the first and second main faces to each other and opposing each other, a plurality of insulator layers being laminated in an opposing direction of the first and second main faces; a plurality of first inner electrodes arranged within the capacitor body; a plurality of second inner electrodes alternately arranged with the plurality of first inner electrodes within the capacitor body such that each pair of the first and second inner electrodes adjacent to each other oppose each other with at least one of the plurality of insulator layers therebetween; a first terminal electrode electrically connected to the plurality of first inner electrodes; a second terminal electrode electrically connected to the plurality of second inner electrodes; a connecting conductor electrically connected to the plurality of first inner electrodes; and an insulator arranged between the first terminal electrode and connecting conductor; wherein the insulator covers the whole area of the connecting conductor; wherein the second terminal electrode is arranged on the second side face of the capacitor body; wherein each of the first inner electrodes includes a main electrode portion and a first lead portion extending from the main electrode portion; wherein an end of each first lead portion is exposed to the first side face; wherein at least one first inner electrode out of the plurality of first inner electrodes further includes a second lead portion extending from the main electrode portion; wherein an end of the second lead portion is exposed to the first side face; wherein the connecting conductor is arranged between the first terminal electrode and first side face wherein the connecting conductor continuously covers all the ends of the first lead portions of the plurality of first inner electrodes exposed to the first side face of the capacitor body without covering the end of the second lead portion of the at least one first inner electrode exposed to the first side face of the capacitor body, and be mechanically connected to the ends of the first lead portions; wherein the insulator is kept from covering the end of the second lead portion of the at least one first inner electrode exposed to the first side face of the capacitor body; and wherein the first terminal electrode is arranged on the first side face, continuously cover the whole area of the insulator and the end of the second lead portion of the at least one first inner electrode exposed to the first side face, and is electrically connected to the second lead portion of the first inner electrode.
