ABSTRACT:
A multilayer capacitor has a capacitor element body in which a plurality of insulator layers are laminated, first and second terminal electrodes, a first internal electrode group, and a second internal electrode group. The first and second terminal electrodes are disposed on an external surface extending in a direction parallel to a laminating direction of the insulator layers, among external surfaces of the capacitor element body. The first internal electrode group has a first internal electrode connected to the first terminal electrode, and a second internal electrode connected to the second terminal electrode. The second internal electrode group has a third internal electrode connected to the first terminal electrode, a fourth internal electrode connected to the second terminal electrode, and at least one intermediate internal electrode not connected to the first and second terminal electrodes. The first and second internal electrodes are arranged with the insulator layer in between so as to form a capacitance component between the first and second internal electrodes. The third and fourth internal electrodes and the intermediate internal electrode are arranged with the insulator layer in between so as to form two or more capacitance components between the third and fourth internal electrodes.
