ABSTRACT:
A multilayer capacitor comprises a capacitor body, a first connecting conductor arranged on a first side face of the capacitor body, first and second terminal electrodes, and a first insulator arranged between the first connecting conductor and first terminal electrode. The capacitor body has a plurality of laminated insulator layers and a plurality of first and second inner electrodes. The second terminal electrode is connected to the second inner electrode. Each of the first inner electrodes has a first lead portion exposing an end to the first side face. At least one of the first inner electrodes also has a second lead portion whose end is exposed to the first side face. The first connecting conductor continuously covers all the ends of the first lead portions of the first inner electrodes and mechanically connects with the ends of the first lead portions. The first terminal electrode continuously covers the whole area of the first insulator and the ends of the second lead portions of the first inner electrodes exposed to the first side face, and is electrically connected to the second lead portions of the first inner electrodes.
