1. A multi-terminal capacitor comprising a capacitor body shaped like a rectangular parallelepiped, the capacitor body including a capacitance forming portion configured to form capacitance between a first conductor film and a second conductor film facing each other with a dielectric film being interposed therebetween,
wherein, when first, second and third directions respectively denotes a direction in which two opposing surfaces of the capacitor body face each other, a direction in which other two opposing surfaces face each other, and a direction in which the remaining two opposing surfaces face each other, first, second and third external terminals are provided on one of surfaces of the capacitor body in the third direction,
wherein the first and second external terminals are electrically connected to the first conductor film,
wherein the third external terminal is electrically connected to the second conductor film,
wherein fourth, fifth and sixth external terminals are provided on the other of the surfaces of the capacitor body in the third direction,
wherein the fourth and fifth external terminals are electrically connected to the first conductor film,
wherein the sixth external terminal is electrically connected to the second conductor film,
wherein the first, second and third external terminals are configured such that the capacitance formed by the capacitance forming portion is extracted by the first, second and third external terminals,
wherein the fourth, fifth and sixth external terminals are configured such that the capacitance formed by the capacitance forming portion is extracted by the fourth, fifth and sixth external terminals,
wherein, on one of the surfaces of the capacitor body in the third direction, the first external terminal is provided on one of edges of the capacitor body in the first direction, the second external terminal is provided on the other of the edges of the capacitor body in the first direction and positioned away in the first direction from the first external terminal, and the third external terminal is interposed between the first and second external terminals and in contact with neither the first nor second external terminal, and
wherein, on the other of the surfaces of the capacitor body in the third direction, the fourth and fifth external terminals are provided on one of edges of the capacitor body in the second direction and positioned at respective sides thereof such that the fourth and fifth external terminals are spaced away from each other in the first direction, the sixth external terminal is provided on the other of the edges of the capacitor body in the second direction and spaced away from the fourth and fifth external terminals in the second direction.
