Description
この電池は、端子固定部の先端部に外装部材の加圧部が押し当たり、端子固定部が変形している。外装部材の変形規制部によって端子固定部の外周面の変形が規制されているので、端子固定部は内側面が内径側に膨出する。これによって、端子固定部に挿通された電極端子が端子固定部に強固に固定されている。
これに対し、本実施形態に係る電池は、図1に示すように、端子固定部40に外装部材60が被せられているので、端子固定部40の外周面40bの変形を規制することができる。また、この場合、外装部材60は、端子固定部40とは材料を代え、より強度の高い材料を用いることができ、これにより、端子固定部40の外周面40bの変形をより強固に規制することができる。このため、端子固定部40が外径側に膨出するのを防止し、端子固定部40の内径側への膨出を増大させることができ、電極端子30を保持する力を増大させることができる。
