Abstract: This non-aqueous electrolyte secondary battery comprises: a separator that has an adhesive on at least one surface thereof; and an electrode that has a core and an electrode mix layer, and that is configured so that the electrode mix layer abuts the adhesive. The electrode mix layer is configured so that the density, in the thickness-direction, of a porous body increases from the core towards the adhesive.
