PROBLEM TO BE SOLVED: To provide a battery pack for which work man-hours can be reduced by reducing the number of components to simplify the assembling work process of the battery pack, and a manufacturing cost can be reduced. SOLUTION: A plurality of thin batteries 10 are laminated in the thickness direction of the thin battery 10, and electrode tabs 14, 15 adjoining each other in the laminating direction are connected each other, and a plurality of the thin batteries 10 are electrically connected in series and/or in parallel to form this battery pack 1. A projecting or recessed engagement part 21 to get engaged with a connector 26 for voltage detection by inserting it is molded in at least one electrode tab 14, 15 of a plurality of the electrode tabs 14, 15 adjoining each other while being overlapped in the laminating direction.
