Abstract:
1. A multilayer capacitor comprising: a capacitor body having a multilayer structure including a plurality of stacked dielectric layers, and having a substantially rectangular parallelepiped shape including a first principal surface and a second principal surface extending substantially parallel to surfaces of the plurality of dielectric layers and opposed to each other, a first side surface and a second side surface opposed to each other, and a first end surface and a second end surface opposed to each other, the first and second end surfaces having a length greater than a length of the first and second side surfaces; and a single first external electrode and a single second external electrode provided on the first end surface and on the second end surface of the capacitor body, respectively, such that no other external electrodes are provided on either of the first end surface or the second end surface; wherein the capacitor body includes at least two first capacitor portions and at least one second capacitor portion which are arranged such that the at least one second capacitor portion is sandwiched between the at least two first capacitor portions in a direction in which the plurality of dielectric layers are stacked; each of the at least two first capacitor portions includes at least one first internal electrode and at least one second internal electrode opposed to each other with a respective one of the plurality of dielectric layers disposed therebetween to provide electrostatic capacity; the at least one second capacitor portion includes at least one third internal electrode and at least one fourth internal electrode opposed to each other with a respective one of the plurality of dielectric layers disposed therebetween to provide electrostatic capacity; each of the at least one first internal electrode includes a first capacity portion and a first lead portion which is led out from the first capacity portion to extend to the first end surface and which is electrically connected to the first external electrode; each of the at least one second internal electrode includes a second capacity portion opposed to the first capacity portion via a respective one of the plurality of dielectric layers, and a second lead portion which is led out from the second capacity portion to extend to the second end surface and which is electrically connected to the second external electrode; each of the at least one third internal electrode includes a third capacity portion and a third lead portion which is led out from the third capacity portion to extend to the first end surface and which is electrically connected to the first external electrode; each of the at least one fourth internal electrode includes a fourth capacity portion opposed to the third capacity portion via a respective one of the plurality of dielectric layers, and a fourth lead portion which is led out from the fourth capacity portion to extend to the second end surface and which is electrically connected to the second external electrode; and the first lead portion and third lead portion are arranged to partially overlap each other when viewed from the direction in which the plurality of dielectric layers are stacked; and an exposed portion of the first lead portion that is exposed at the first end surface has a greater width than an exposed portion of the third lead portion that is exposed at the first end surface.
