<p>[Problem] To improve efficiency when the temperature of a power storage unit is adjusted. [Solution] A power storage device (1) is provided with: a plurality of power storage units (10) which are arranged in a row in a first direction (X direction); and spacers forming a space (S) in which a heat exchange medium that is employed for adjusting the temperature of the power storage units is moved in a second direction (Z direction) orthogonal to the first direction, between two adjacent power storage units. The spacers have, at two mutually opposing faces which form the space, projections (16) which project towards the inside of the space. The projections, which are respectively provided on the two faces, are offset in the second direction with respect to positions that are mutually opposing in the first direction.</p> |
