Abstract

A trimming capacitor wherein its trimming direction has no directivity. The trimming capacitor comprises a dielectric ceramic sheet provided with a trimming capacitor electrode on the surface thereof, a dielectric ceramic sheet provided with internal capacitor electrodes on the surface thereof, and other sheets. Regions where the trimming capacitor electrode overlaps with the internal capacitor electrodes are disposed so as to be linearly symmetrical about a base line which is inclined by 45.degree. with respect to a long side of the trimming capacitor. Therefore, the trimming electrode can be trimmed in the same way in either the X or the Y direction of the trimming electrode.
