Abstract: A power storage module includes a plurality of power storage devices and a bus bar electrically connecting the plurality of power storage devices. Each power storage device has a housing and a pair of output terminals disposed on a first surface of the housing. The bus bar has the plurality of terminal connections connected to the output terminals of each power storage device, and a linking part connecting the plurality of terminal connections. Each terminal connection part has a first part connected to each output terminal and a second part continuous from the first part and extending along a second surface spreading in a direction intersecting the first surface of the housing. Each linking part has a third part that connects the second parts of the adjacent terminal connections to each other.
