Title:
VARIABLE CAPACITANCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/136771
Kind Code:
A1
Abstract:
A variable capacitance element is provided which is characterized by comprising multiple variable capacitance layers which are configured from a dielectric material, multiple pairs of electrodes which are positioned on both primary surfaces of the variable capacitance layers and face one another with a variable capacitance layer therebetween, multiple insulating units and at least one pair of extraction units, and is characterized in that the multiple variable capacitance layers and the multiple insulating units are alternately laminated together to form a laminate, the variable capacitance layers and the pairs of electrodes configure multiple capacitor structures, and the extraction unit is electrically connected at one end to an electrode configuring a capacitor structure, passes through an insulating unit, and is electrically connected at the other end to an external electrode or another electrical element.
