Abstract
【解決手段】 電子部品は、チップ素体2と、このチップ素体2の一方の主面2aに形成された外部電極3Aとを備えている。外部電極3Aは、チップ素体2の主面2aに接合された第1電極層10と、この第1電極層10の縁部の内側領域に積層されるように接合された第2電極層11とを有している。第2電極層11の先端面11aは、平坦状となっている。第2電極層11における第1電極層10との接合部分には、第1電極層10に対して末広がりとなるようなR状部13が設けられている。第1電極層10におけるチップ素体2との接合部分には、チップ素体2に対して末広がりとなるようなR状部15が設けられている。第1電極層10は印刷法により形成され、第2電極層11は電極シートにより形成される。
