Multilayer capacitor

A multilayer capacitor comprising:

• a multilayer body of rectangular parallelepiped shape constructed by stacking a plurality of rectangular dielectric layers on top of one another in a stacking direction;
• a first internal capacitor electrode and a second internal capacitor electrode, which are disposed in a plural number, arranged in an alternating manner so as to be opposed to each other, with the dielectric layer interposed therebetween inside the multilayer body, the first internal capacitor electrode and the second internal capacitor electrode each having capacitor electrode lead-out portions led out to a left-hand surface and a right-hand surface, respectively, of the multilayer body that are perpendicular to the stacking direction and a direction parallel with a longitudinal direction of the dielectric layer;
• a first external relay electrode formed on each of the left-hand surface and the right-hand surface of the multilayer body, to which is connected the capacitor electrode lead-out portion of the first internal capacitor electrode;
• a second external relay electrode formed on each of the left-hand surface and the right-hand surface of the multilayer body, to which is connected the capacitor electrode lead-out portion of the second internal capacitor electrode;
• a first internal relay electrode disposed between dielectric layers different from the dielectric layers corresponding to the first internal capacitor electrode and the second internal capacitor electrode inside the multilayer body, which has relay electrode lead-out portions led out to the left-hand surface and the right-hand surface, respectively, and connected to the first external relay electrode, and also has extension portions extended to an upper surface and a lower surface, respectively, of the multilayer body that are perpendicular to the stacking direction and a direction parallel with a width direction perpendicular to the longitudinal direction of the dielectric layer;
• a second internal relay electrode disposed between dielectric layers different from the dielectric layers corresponding to the first internal capacitor electrode and the second internal capacitor electrode so as to be opposed to the first internal relay electrode, with the dielectric layer interposed therebetween, inside the multilayer body, which has relay electrode lead-out portions led out to the left-hand surface and the right-hand surface, respectively, and connected to the second external relay electrode, and also has extension portions extended to the upper surface and the lower surface, respectively, of the multilayer body;
• a first external terminal electrode formed on each of the upper surface and the lower surface of the multilayer body, to which is connected the extension portion of the first internal relay electrode;
• and
• a second external terminal electrode formed on each of the upper surface and the lower surface of the multilayer body, to which is connected the extension portion of the second internal relay electrode,
• wherein only one of the two surfaces selected from the group consisting of the upper surface and the lower surface is configured for use as a mounting surface, wherein the mounting surface is opposed to a circuit board.
