Non-aqueous electrolyte secondary battery

A non-aqueous electrolyte secondary battery, comprising:

• an electrode assembly in which a first electrode and a second electrode having different polarities from each other are wound with a separator interposed therebetween;
• an electrolyte liquid;
• and
• a cylindrical exterior housing can housing the electrode assembly and the electrolyte liquid, wherein
• the first electrode has a current collector and a mixture layer stacked on at least a part of a surface of the current collector,
• a plurality of exposed portions where the current collector is exposed is formed on a surface of the first electrode along a winding direction of the electrode assembly, and a tab is connected to each of the exposed portions, and
• when a rotation angle from an end on an initial winding side to an end on a terminal winding side of the exposed portion relative to a winding center of the electrode assembly is defined as an exposed portion angle, an exposed portion angle of the exposed portion positioned on the initial winding side is larger than an exposed portion angle of the exposed portion positioned on the terminal winding side.
