ABSTRACT:
A miniature variable capacitor comprises a base plate having a base plate main part having stator support poles embedded in one surface of said base plate main part and mounting plate parts extending from said base plate main part in lateral directions and adapted to be fitted to a mount member different from said miniature variable capacitor, and a miniature variable capacitor main body comprising a rotor shaft rotatably supported at the center of said base plate main part, stator plate groups fixedly supported on said stator shafts, and rotor plate groups fixedly supported on said rotor shaft. The base plate further has bent parts bent in the direction in which said stator poles project and formed between said base plate main part and said mounting plate parts and integral therewith, whereby said mounting plate parts is not on the same level as said base plate main part but stepped in the stator support poles projecting direction from said base plate main part.
