Abstract
A feedthrough ceramic capacitor having a grounding fitting provided in a part of a housing of the capacitor is mounted to a filter box by being forced into the latter through an insertion hole of the filter box. Since a corrugated edge is provided around the entire circumference of the insertion hole provided in the filter box, the feedthrough ceramic capacitor can be forced into the filter box easily. Further, because no gap is generated between the filter box and the grounding fitting, high-frequency noise in the inside of the filter box never leaks to the outside.
