PROBLEM TO BE SOLVED: To provide a battery pack which seals battery cells.SOLUTION: A battery pack 12 houses battery cells 16 and may be attached to and removed from a tool body. The battery pack 12 includes: a circuit board 20 which holds a battery side terminal 21 connected with the battery cells 16; a closed container 40 which covers the battery cells 16; and an opening 44 which is provided in the closed container 40 and exposes the battery side terminal 21 to the exterior of the closed container 40. A space between an edge 45 forming the opening 44 and the circuit board 20 is sealed by an adhesion part 46. 【課題】電池セルをシールすることのできる電池パックを提供する。【解決手段】電池セル１６を収容し、かつ、工具本体に取り付け及び取り外しが可能な電池パック１２であって、電池セル１６に接続された電池側端子２１を保持する回路基板２０と、電池セル１６を覆う密閉容器４０と、密閉容器４０に設けられ、電池側端子２１を密閉容器４０の外部に露出させる開口部４４と、を有し、開口部４４を形成する縁４５と回路基板２０との間を、接着部４６でシールした。【選択図】図５
