트레이의 하측 플랜지부와 커버의 상측 플랜지부를 중첩시킨 상태에서, 이들 사이에 필요한 실링제를 존재시켜 충분한 실링 성능을 얻을 수 있는 전지 팩을 제공한다. 트레이와 상기 트레이를 덮는 커버에 의해, 단일 전지의 패키징 케이스가 구성된다. 그리고, 트레이의 하측 플랜지부 및 커버의 상측 플랜지부 중 적어도 어느 한쪽은, 서로 중첩된 상태에서, 서로 대향하는 대향면에 있어서의 적어도 일부에, 상대방의 대향면으로부터 이격(離隔)되는 이격부를 구비하고, 상기 이격부 상에, 실링제가 배치된다.
Provided is a battery pack that ensures sufficient sealing performance between a tray and a cover by arranging a necessary sealing member between a lower flange portion of the tray and an upper flange portion of the cover that are held in abutment with each other. The tray and the cover covering the tray constitute a packaging case of electric cells. At least a part of a facing surface of at least one of the lower flange portion of the tray and the upper flange portion of the cover that abut each other forms a non-abutting portion that is located apart from the facing surface of the opposite flange portion, and a sealing member is arranged on the non-abutting portion.
