Abstract: A power storage module includes a first power storage device, a second power storage device, a first holder, a second holder, and a reinforcement member. The first power storage device and the second power storage device are arranged in an orthogonal direction. The first holder includes a first side plate. The second holder includes a second side plate. The reinforcement member includes a first reinforcement part, a second reinforcement part, and a first connection part. The first reinforcement part includes a side plate groove into which the first side plate is fitted. The second reinforcement part includes a side plate groove into which the second side plate is fitted. The first connection part connects the first reinforcement part and the second reinforcement part, and is at least temporarily slidable with respect to at least one of the first reinforcement part and the second reinforcement part.
