PROBLEM TO BE SOLVED: To provide a composite capacitor which is small in size and good in capacitance value accuracy. SOLUTION: The composite capacitor comprises a laminated substrate S. The substrate includes a plurality of dielectric layers 1, first and second electrodes 2, 3 formed as a plurality of conductor layers, and a first common electrode 4. The layers and electrodes are alternately laminated. Since the first and second electrodes 2, 3 and the first common electrode 4 are laminated in a vertical direction, the dimension of the capacitor in a horizontal direction can be made smaller than that of a prior art. The first and second electrodes 2, 3 are opposed to each other within the surface area of the first common electrode 4. Thus, even if the first and second electrodes 2, 3 are stacked to be shifted from the first common electrode 4 during the lamination of the laminated substrate S, the first and second electrodes 2, 3 can be avoided from being shifted to the outside of the surface area of the first common electrode 4, the capacitor can have an accurate capacitance value, can be reduced in stray capacitance, and can be improved in circuit characteristics.
