Claims

[Scope of utility model registration request]

A cylindrical dielectric (a), an internal electrode (b) continuously formed from at least a portion of the inner circumferential wall surface of the cylindrical portion of the dielectric body to a portion of the outer circumferential wall surface of the cylindrical portion, and the internal electrode on the remaining portion of the outer circumferential wall surface. The capacitor is a cylindrical capacitor consisting of an external electrode C formed insulated from the external electrode C, and the upper surfaces of said B and C are entirely covered with an interior coat of insulating resin except for the annular exposed electrode portions formed at both ends of the cylinder. Each of the electrodes is coated with an exterior coat, and the planar portions perpendicular to the cylindrical generatrix at both ends of A are covered with a conductor, and a plating process is applied to the conductor and the exposed annular electrode portion. A cylindrical capacitor characterized in that enlarged terminal electrodes are formed.
