To secure a wide storage space in a battery pack without making its outer shape large.SOLUTION: A battery pack comprises: one or more secondary battery cells 1; a circuit board 4 mounted with a circuit connected electrically to the secondary battery cells 1; a holder part 20 including a space defined with one or more wall parts 8 as a storage space 9 and having one surface, communicating with the storage space 9, opened; a cover part 26 connected to the wall parts 8 to close the opening part of the holder part 20; and an outer package label 3 stuck on surfaces of the holder part 20 and the cover part 26 with the opening part of the holder part 20 closed with the cover part 26. The battery pack is coupled through a fitting coupling part 7 consisting of a fitting recessed part 7A and a fitting projection part 7B formed by forming the wall parts 8 and the cover part 26 in a dovetail shape in plan view.SELECTED DRAWING: Figure 6 【課題】パック電池の外形を大きくすることなく、内部の収納空間を広く確保する。【解決手段】電池パックは、一以上の二次電池セル１と、二次電池セル１と電気的に接続された回路を実装した回路基板４と、一以上の壁部８で画成された空間を収納空間９として、収納空間９と連通する一面を開口したホルダ部２０と、壁部８に連結されて、ホルダ部２０の開口部を閉塞するカバー部２６と、ホルダ部２０の開口部をカバー部２６で閉塞した状態で、ホルダ部２０とカバー部２６の表面に貼付される外装ラベル３とを備えている。電池パックは、壁部８とカバー部２６を、平面視において蟻溝形状に形成してなる嵌合凹部７Ａと嵌合凸部７Ｂとからなる嵌合連結部７を介して連結している。【選択図】図６
