PROBLEM TO BE SOLVED: To facilitate removal between a rectangular battery and a joined body, with the use of a jig.SOLUTION: In a battery module, a rectangular battery 31 and a heat transfer plate 41, which are held in a battery holder, are alternately arranged in line. The rectangular battery 31 has: a first face 32; and a third face 34 which connects the first face 32 to a second face 33 and is bent from the first face 32 to the second face 33. The heat transfer plate 41 has: a body 42 with a rectangular flat-plate shape; a first extension part 43 extending in the thickness direction of the body 42; and a second extension part. The body 42 and the first extension part 43 are connected to each other via a first bent part 45 which is bent from the body 42 to the first extension part 43. Further, the body 42 and the second extension part are connected to each other via a second bent part which is bent from the body 42 to the second extension part. A gap 61 is formed between the rectangular battery 31 and the heat transfer plate 41. |
