Abstract
A capacitance element body is configured by two or more capacitors, the capacitors being formed of a dielectric layer and at least three internal electrodes, the internal electrodes each being laminated via the dielectric layer and arranged to allow a center of gravity of an electrode body forming electrostatic capacitance to be arranged on a straight line in a lamination direction. In the capacitance element body, said two or more capacitors are serially connected in a lamination direction of the internal electrodes. Furthermore, external terminals, each being electrically connected to an electrode body forming electrostatic capacitance, are formed in side surfaces of the capacitance element body.
