A capacitor includes a dielectric layer, a first conductive layer, a second conductive layer, first inner electrodes, second inner electrodes, a first external power electrode layer, a second external power electrode layer, a first outer electrode, and a second outer electrode. The first and second inner electrodes and first and second second outer electrodes are a conductive material. The dielectric layer has through-holes connecting with a first main surface and a second main surface. The first inner electrodes are in a first set of the through-holes and connected to the first conductive layer. The second inner electrodes are in a second set of the through-holes and connected to the second conductive layer. The first outer electrode is on the first external power electrode layer and some side-faces of the dielectric layer. The second outer electrode is on the second external power electrode layer and some side-faces of the dielectric layer.
