Abstract
The present invention relates to a through-type capacitor having a cylindrical dielectric and a through terminal inserted into the former. The characteristics of the capacitor of the present invention reside in that the through terminal inserted into a through-hole drilled in the dielectric is in the form of a metallic pipe provided with a plurality of slits at equal intervals and the parts of the metallic pipe separated by the slits are soldered to a metallized inner wall surface of the through-hole serving as an electrode. With the above structure, the capacitor of the present invention has the advantages that since the metallic pipe having a plurality of slits is used as a through terminal, the thermal stress and the bending force applied on the dielectric at the time of thermal expansion of the terminal due to a temperature change are sharply reduced and the terminal can be easily manufactured without requiring much time and labor for coating a solder resist on the terminal as has been the case with the prior art technique.
