Abstract
An electronic component includes a ceramic element, glass-containing Au layers formed on both surfaces of the ceramic element, and an Au—Sn alloy layer formed on at least one of the glass-containing Au layers; the electronic component further includes a pure-Au layer between the glass-containing Au layer and the Au—Sn alloy layer; furthermore, the Au—Sn alloy layer has an Au—Sn eutectic structure.
