セラミツク可変コンデンサ。 A ceramic dielectric member having a stator electrode formed on one side thereof, a rotor member having a rotor electrode opposite to the stator electrode via the ceramic dielectric member, and an engagement surface that engages with the rotor member. The stator electrode and the rotor electrode are provided with a rotating shaft formed with a fitting portion and a flange portion that regulates the axial position of the rotor member, and by rotating the rotor member via the rotating shaft, the stator electrode and the rotor electrode are rotated. In a ceramic variable capacitor in which the capacitance is made variable by changing the facing area of the capacitor, a capacitor having a radius smaller than the distance between the engaging surface and the center of the rotating shaft is provided adjacent to the fitting portion and the flange portion. A ceramic variable capacitor characterized by a relief groove for cutting tools.
