This battery pack (30) is provided with a front casing (31) and a plurality of battery modules. Each battery module has a cylindrical battery group (42) and connection members (46). In the cylindrical battery group (42), a plurality of cylindrical batteries (42a) are aligned in a direction that is perpendicular to the axial direction to form a first space (43) between the cylindrical batteries and an inner wall of the front casing (31) when viewed in the axial direction. The connection members (46) are fitted to both ends of the cylindrical battery group (42) in the axial direction so as to connect the terminals of the cylindrical batteries (42a). The battery modules are aligned in the axial direction, and the connection members (46) of battery modules adjacent to each other are affixed to each other at portions that are positioned in the first space (43).
