Abstract:
1. A feedthrough capacitor comprising: a capacitor element body of a substantially rectangular parallelepiped shape in which a plurality of insulator layers are laminated together; a signal internal electrode and a ground internal electrode arranged in the capacitor element body and facing each other; signal terminal electrodes provided on first and second end faces, respectively, in a longitudinal direction of the capacitor element body and connected to the signal internal electrode; and ground terminal electrodes provided on first and second side faces, respectively, of the capacitor element body, extending along the longitudinal direction of the capacitor element body and facing each other, said ground terminal electrodes being connected to the ground internal electrode, wherein the ground terminal electrodes comprise first and second ground terminal electrodes on the first side face, the first ground terminal electrode located closest to the first end face on the first side face, the second ground terminal electrode located closest to the second end face on the first side face, and third and fourth ground terminal electrodes on the second side face, the third ground terminal electrode located closest to the first end face on the second side face, and the fourth ground terminal electrode located closest to the second end face on the second side face, wherein, when viewed from a direction perpendicular to the first side face, a distance between the first ground terminal electrode and second ground terminal electrode is longer than a distance between the first ground terminal electrode and the first end face and a distance between the second ground terminal electrode and the second end face, wherein, when viewed from a direction perpendicular to the second side face, a distance between the third ground terminal electrode and fourth ground terminal electrode is longer than a distance between the third ground terminal electrode and the first end face and a distance between the fourth ground terminal electrode and the second end face, and wherein none of terminal electrodes are arranged on a region located between the first and third ground terminal electrodes and the second and fourth ground terminal electrodes in the capacitor element body.
