A variable capacitor includes a plurality of stator plates supported on spaced parallel rods. A plurality of rotor plates supported on a shaft are arranged so that each rotor plate is placed a predetermined distance from the surface of the adjacent stator plate. This is accomplished by spacer members disposed between the adjacent stator plates as well as between the adjacent rotor plates. Each spacer member is made of metal wire, with a circular cross-section, and is shaped in form of a ring. Use of the metal wire having a predetermined dimension is much more convenient than a tube or sleeve. Consequently fixing the distance between the stator plates and between the rotor plates can be performed with high accuracy.
