METHOD FOR MANUFACTURING BATTERY MODULE, AND JIG

There is provided a method for manufacturing a battery module. The battery module includes a stacked body in which units are stacked. Each unit includes a first cell group and a second cell group in which cells are arranged, and a temperature control plate. The method includes: disposing a first jig including a first elastic body across the first cell group on a first side of the temperature control plate; disposing a second jig including a second elastic body across the second cell group on a second side of the temperature control plate; and pressing the first cell group and the second cell group against the temperature control plate by bringing the first jig and the second jig close to each other such that the first elastic body is in contact with the first cell group and the second elastic body is in contact with the second cell group.
