The purpose of the present invention is to provide a battery module structure which makes heat conduction between a coolant and a cooling plate good by a coolant channel having a relatively simple structure and thus makes the temperature distribution of the cooling plate more uniform, thereby making the temperatures of a plurality of single cells uniform. A battery module (100) of the present invention comprises a plurality of cells (10), a cooling plate (1), and a channel (2) that is formed within the cooling plate. The channel (2) has: a first channel part (2A) that extends in the alignment direction of the plurality of cells (10); a second channel part (2C) that extends in the alignment direction parallel to the first channel part (2A) with a first partition wall part (3A) being arranged therebetween; and a first communication part (2B) which communicates an end of the first channel part (2A), said end being on one side of the alignment direction, and an end of the second channel part (2C), said end being on the side of the alignment direction, with each other and turns the flow direction of the coolant in the first channel part (2A) and the second channel part (2C). |
