Abstract
In a laminate-type power storage element, laminated films forming an exterior body are each formed by sandwiching a metal layer between a resin layer and a heat sealing layer. An electrode body includes a positive electrode and a negative electrode disposed opposite to each other across a separator and is enclosed together with a non-aqueous organic electrolyte solution inside the exterior body. Particles included in the positive electrode or negative electrode have a D90 particle size less than or equal to the thickness of the heat sealing layer.
