Non-aqueous electrolyte secondary battery

A non-aqueous electrolyte secondary battery comprising:

• a positive electrode;
• a negative electrode facing the positive electrode;
• and
• a non-aqueous electrolyte, wherein:
• the positive electrode includes
• a positive electrode current collector,
• a positive electrode active material layer which is provided on a part of a surface of the positive electrode current collector and contains a positive electrode active material, and
• an insulating layer which is provided on other parts of the surface of the positive electrode current collector and contains an inorganic filler;
• the negative electrode includes
• a negative electrode current collector, and
• a negative electrode active material layer which is provided on a part of a surface of the negative electrode current collector and contains a negative electrode active material;
• and
• the insulating layer includes
• a first insulating layer disposed along an end portion of the positive electrode active material layer, and
• a second insulating layer formed at a position which is separated from the first insulating layer and faces an end portion of the negative electrode active material layer;
• wherein the first insulating layer and the second insulating layer are separated from each other in the width direction of the positive electrode;
• and
• wherein the first insulating layer, non-coated portion, and the second insulating layer are positioned in this order in the width direction of the positive electrode.
