ABSTRACT:
A variable capacitor includes a generally cylindrical insulating case made of synthetic resin, with a stator terminal, which has springiness at its contact portion, insert-molded therein. A dielectric body, having a stator electrode formed thereon, is nonrotatably housed in the insulating case along with a rotatable metal rotor having a rotor electrode, and a non-rotatable rotor terminal. The rotor terminal has springiness at its contact portion and is formed with an aperture through which the metallic rotor may be rotated for adjustment.
