Abstract
In a stacked battery including a plurality of electrolyte layers having substantially the same resistance value, an uneven temperature distribution during charge and discharge changes the resistance values of solid electrolyte layers to cause variations in output among a plurality of unit cells in a stacking direction. A power storage device includes a plurality of electrolyte layers which are stacked with an electrode element interposed between them, wherein the plurality of electrolyte layers include an electrolyte layer provided at a first position in a stacking direction and an electrolyte layer provided at a second position different from the first position, heat radiation being lower at the second position than at the first position, and the electrolyte layer at the second position has a resistance value higher than that of the electrolyte layer at the first position.
