| Zusammenfassung: | A non-aqueous electrolyte secondary battery includes: a positive electrode plate; a negative electrode plate; and a separator disposed between the positive electrode plate and the negative electrode plate. The separator includes a porous resin layer. The porous resin layer is made of polyolefin having a melting point of 80° C. or more and 135° C. or less. At least one of the positive electrode plate and the negative electrode plate has a surface facing the porous resin layer. The surface forms a contact angle of 30° or more with a molten droplet of the polyolefin. |
