Abstract
A power source device includes: a plurality of batteries each including a discharge valve that opens when an internal pressure becomes higher than a set pressure and jets emission gas; outer case that houses these batteries and is composed by providing discharge opening that discharges, to an outside, the emission gas from the discharge valve; and heat-resistant plate that is a part of outer case and is composed by being disposed in a facing attitude in an inside of exhaust surface () composed by providing discharge opening, wherein heat-resistant plate is: provided with, along an outer peripheral edge, energy attenuation gap between the heat-resistant plate itself and an inner surface of the outer case; provided with planar heat radiation gap between the heat-resistant plate itself and an inner surface of the exhaust surface; and composed to cause the emission gas jetted from the discharge valves to pass through energy attenuation gap and heat radiation gap, and to be discharged from discharge opening to an outside.
