Abstract
A variable capacitance element includes variable capacitance layers made of a dielectric material, paired electrodes located on both main surfaces of the variable capacitance layers opposite to each other across the variable capacitance layers, insulating elements; and at least one pair of lead-out elements. The variable capacitance layers and the insulating elements are alternately laminated to provide a laminated body. The variable capacitance layers and the paired electrodes define capacitor structures, and the lead-out elements are electrically connected at one end thereof to an electrode defining the capacitor structures, penetrate the insulating elements, and are electrically connected at the other end to external electrodes or other electrical elements.
