An electronic component has a casing. An electrically-conductive body enclosed in the casing. The inner end of a lead is welded to the electrically-conductive body. The outer end of the lead projects outward out of the casing through a through hole formed in the casing. An enlarged portion is formed in the lead at a position between the inner end and the outer end. The enlarged portion is set in the through hole to close the through hole. Even if whiskers are generated at a position between the electrically-conductive body and the lead based on stress generated during a welding process, the whiskers are received on the enlarged portion in the through hole. No whisker falls out of the casing through the through hole.
