    • In order to obtain a stator of a variable capacitor, prepared is a ceramic laminate having a stator electrode provided in its interior and a plurality of burnaway films of carbon or resin, which can be burned away by firing, provided in positions corresponding to that of a concave portion in the form of layers. This ceramic laminate is fired to burn out the burnaway films thereby obtaining a sintered body provided with a plurality of cavities and a plurality of thin layers, and this sintered body is barrel-polished to crush the thin layers, thereby forming a concave portion. A rotor of a metal forming a rotor electrode is arranged on the stator obtained in the aforementioned manner. A cover of a metal is fixed to the stator through an engaging member engaging in the concave portion of the stator, to rotatably store the rotor while pressing the rotor against the stator by a spring action part.

    • In a variable capacitor having a stator with a stator electrode and a rotor with a rotor electrode both of which are housed in a recess section of a casing while allowing the recess section to be closed by a cover, enabling the rotor to be brought into stable close contact with the stator. To this end, a cover (46) made of a chosen metal includes a cover main body (55) which covers the upper opening of a recess section (45) except for an adjustment hole (54) that exposes a driver groove (30) of the rotor (43), leg sections (56, 57) which engage a casing (44) letting the cover main body (55) be secured to the casing (44), and a rotor terminal. The cover main body (55) has a size corresponding to the outer diameter of the variable capacitor (41). This cover main body (55) may have a vent shape so as to create intended elastic force which may act to compress the rotor (43) against the stator (42). More preferably, a spring washer (60) is provided which integrally extends from the cover main body (55) and is folded so that it is placed between the cover main body (55) and the rotor (43).
