Abstract
Abstract A ceramic electronic component which comprises a generally elongated ceramic body and a metal cap mounted on each end of the ceramic body. Each end of the ceramic body has a peripheral edge rounded to have a predetermined first radius of rounding, and the metal cap has an interior corner rounded to have a predetermined second radius of rounding. The first radius of rounding is greater than the second radius of rounding.
