The purpose of the present invention is to prevent contact between an adjacent assembled battery and a refrigerant. This power source device is equipped with a plurality of assembled batteries (2) and a plurality of cooling mechanisms for cooling each of the assembled batteries (2). Each of the cooling mechanisms comprises: a first plate (30) having a mounting surface in thermal contact with the corresponding assembled battery (2); a second plate (31) fixed on the surface on the reverse side from the mounting surface; a cooling flow path (34) formed between the first plate (30) and the second plate (31); and a seal part (32) disposed between the first plate (30) and the second plate (31) for the purpose of sealing the cooling flow path (34). The first plate (30) has a side wall (33) enclosing the region in which the seal part (32) is disposed. In an orthogonal direction to the mounting surface, the forward extremity of the side wall (33) extends to a farther position from the corresponding assembled battery (2) than the position of the seal part (32). |
