Title:
VARIABLE CAPACITANCE CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2014/058004
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a variable capacitance capacitor configured so that a range of a variable capacitance can be increased and capacitance fluctuations due to influences of acceleration exerted from outside can be suppressed. [Solution] In this variable capacitance capacitor, a movable capacitor electrode part (30) and a movable driving electrode part (31) are linked by linking parts (51) and (52) at which a fulcrum part (61c) is provided; the linking parts (51) and (52) are provided rotatably around the fulcrum part (61c) as a fulcrum; the fulcrum part (61c) is provided so that a rotation radius of the linking parts (51) and (52) linked to the movable capacitor electrode part (30) around the fulcrum part (61c) as a fulcrum is greater than a rotation radius of the linking parts (51) and (52) linked to the movable driving electrode part (31); and the movable capacitor electrode part (30) and the movable driving electrode part (31)are formed so that the mass per unit area of the movable capacitor electrode part (30) is smaller than that of the movable driving electrode part (31).
