Abstract

A multilayer capacitor comprises a multilayer body in which a plurality of dielectric layers and a plurality of first and second inner electrodes are alternately laminated, and first and second terminal electrodes formed on the multilayer body. The plurality of first and second inner electrodes are electrically connected to each other through a connecting conductor. A part of the plurality of first inner electrodes and a part of the plurality of second inner electrodes are electrically connected to the first and second terminal electrodes through lead conductors, respectively. Each first inner electrode connected to the respective first terminal electrode through the lead conductor and each second inner electrode connected to the respective terminal electrode through the lead conductor are arranged at positions symmetrical to each other about the center position in the laminating direction of the multilayer body. Alternatively, one or a plurality of first inner electrodes connected to the first terminal electrode through the lead conductor and one or a plurality of second inner electrodes connected to the second terminal electrode through the lead conductor are arranged at respective positions symmetrical to each other about the center position in the laminating direction of the multilayer body.
