Description
集電体と端子電極とが面接触することにより、これらの間の接触面積が大きくなり、接触信頼性の高いチップ電池を得ることができる。さらに、集電体と端子電極との間の接触面積が大きいため、内部抵抗の小さいチップ電池を得ることができる。
また、固体電解質層、正極層、負極層からなる素体の積層方向と直交する向きの両端側に端子電極が形成されるため、チップ電池の実装面と素体の積層方向とが直交した状態で表面実装を行うことができる。
素体の積層方向に直交する向きの両端側に端子電極が形成されるチップ電池において、それぞれの端子電極側で異なる集電体が露出するように保護膜を形成することにより、その露出部において集電体と端子電極を面接触させることができる。
また、端子電極の回り込み部によって、集電体の露出部と保護膜の両方を覆うように端子電極が形成されるため、保護膜による密閉性(封止性)を確保しつつ、保護膜を含む全体の密着性を向上させることができる。
