Claim:
1. A three-terminal capacitor comprising: a capacitor element including first and second surfaces extending in a length direction and in a width direction, third and fourth surfaces extending in the width direction and in a thickness direction, and fifth and sixth surfaces extending in the length direction and in the thickness direction; a first-side outer electrode that is disposed at a first end portion of the first surface in the length direction and on predetermined areas of the third, fifth, and sixth surfaces; a second-side outer electrode that is disposed at a second end portion of the first surface in the length direction and on portions of the fourth, fifth, and sixth surfaces; a center outer electrode that is disposed at a portion of the first surface between the first-side outer electrode and the second-side outer electrode in the length direction and on portions of the fifth and sixth surfaces; and a plurality of conductor layers including a plurality of first conductor layers and a plurality of second conductor layers that are stacked in the width direction; the plurality of first conductor layers are disposed within the capacitor element, electrically connected to the center outer electrode via a first extending portion at the first surface, and spaced apart from the third and fourth surfaces; the plurality of second conductor layers are disposed within the capacitor element, electrically connected to the first-side outer electrode via first-side second extending portions and to the second-side outer electrode via second-side second extending portions at the first surface, and spaced apart from the third and fourth surfaces; wherein a dimension B′ is greater than a dimension B, where the dimension B′ represents a dimension in the length direction of the center outer electrode on a boundary portion at which the first surface intersects with the fifth surface, and the dimension B represents a dimension in the length direction of the center outer electrode on the first surface; a distance D is greater than a distance C, where the distance D represents a distance in the length direction between the third surface and exposed portions of the first-side second extending portions at the first surface that are nearest to the fifth surface and the sixth surface, and the distance C represents a distance in the length direction between the third surface and an exposed portion of the first-side second extending portion at the first surface that is nearest to a center of the conductor element in the width direction; and the first-side second extending portions overlap each other in the width direction.
