Abrégé
(EN)
The purpose of the present invention is to dissipate heat efficiently using a potting resin, achieve high safety by smoothly discharging ejected gas from a discharge valve, fill a potting resin simplyand efficiently, and ensure heat-dissipation characteristics and safety of a battery. This power supply device is provided with a battery assembly (40) in which a pair of battery units (40A) are arranged in positions opposing an insulating space (6), with discharge openings of discharge valves included in battery cells (1) in the battery units (40A) arranged in the insulating space (6). The battery assembly (40) is in close contact with a potting resin (7). A closing cover (61) made of a foam of an insulating material having closed pores that can be melted by ejected gas from the battery cells (1) is arranged in the insulating space (6). The closing cover (61) blocks flow of the potting resin (7) into discharge valve opening portions.
