Patent attributes
A battery pack includes a laminate battery having a built-in electrode held inside thereof by connecting a first sheathing film and a second sheathing film at lap sections thereof along outer peripheries of the electrode. A terminal substrate is disposed at the lap section and includes output terminals at a front surface side thereof. A substrate holder is disposed between a rear surface of the terminal substrate and the lap section, and a first metal plate is laminated on a first sheathing film side of the laminate battery. In the battery pack, the terminal substrate is supported by the substrate holder, the lap section, and the first metal plate, and the output terminals of the terminal substrate are disposed at positions so as to be brought closer to the same plane as a front surface of the second sheathing film.
