Abstract
Power supply device includes: battery stack formed by stacking a plurality of battery cells; a pair of end plates disposed at both ends of the battery stack; binding bars configured to connect the pair of end plates; lower plate that is brought into contact with heat radiation surfaces of battery cells forming the battery stack and to which heat energy of battery cell is transferred; and heat conductive sheet having plasticity and stacked on a surface of lower plate. In lower plate, contact surface that is brought into contact with heat conductive sheet is regular uneven surface, heat conductive sheet is stacked on uneven surface in a pressed state, heat conductive surface of heat conductive sheet is deformed into a concave shape along uneven surface, and heat conductive sheet and lower plate are stacked on each other in a contact state.
