NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

This non-aqueous electrolyte secondary battery that is an example of an embodiment comprises a winding type electrode body for which a positive electrode and a negative electrode are wound with a separator interposed. The electrode body has a positive electrode lead. The positive electrode lead has: a lead base made of metal that includes a first surface joined to the positive electrode, and a second surface on the side opposite to the first surface; and an insulating ceramic layer principally comprising an inorganic compound and formed over a range within the second surface of the lead base so as to face the negative electrode with at least the separator interposed therebetween.
