ことを特徴とする段付き貫通コンデンサ。 A cylindrical through hole whose central axis is the center axis of the element body in the center of the top-shaped element body having a stepped cylindrical outer shape, and a cylindrical through hole that is larger than the through hole formed continuously at one end. a first exterior comprising a top-shaped capacitor body having a concentric short cylindrical recess with a hole diameter, and comprising a conductor film formed in a continuous layer on the entire inner wall surface from the inner surface of the through hole to the inner surface of the recess; It has an electrode and a second external electrode made of a conductor film formed in a continuous layer on the outer peripheral surface of the capacitor body, and further has a lead wire inserted into the through hole and soldered in the recess. This is a stepped feedthrough capacitor consisting of a stepped feedthrough capacitor, in which the axial end face of the capacitor body and the side surface near the end face following this are masked by applying resist resin, and the surfaces of the capacitor body other than the end face are plated. A stepped feedthrough capacitor, characterized in that a layer is applied to provide said pair of external electrodes.
