Method for manufacturing non-aqueous electrolyte secondary battery, and non-aqueous electrolyte secondary battery

In a method for manufacturing a non-aqueous electrolyte secondary battery, a wound electrode body (S10) is formed and formed into a flat wound electrode body (S12) by press working. A non-aqueous electrolyte secondary battery before inspection is formed by connecting a flat wound electrode body and a lid (S14), integrating a battery case and the lid (S16), injecting a non-aqueous electrolyte through an injection port of the lid, and closing the injection port after injection (S18). Then, the non-aqueous electrolyte secondary battery before inspection is pressed in a predetermined pressed state (S20). A predetermined charge/discharge test is performed on the non-aqueous electrolyte secondary battery in the predetermined pressed state (S22). In a predetermined charge/discharge inspection, if a predetermined inspection specification is satisfied, a non-aqueous electrolyte secondary battery that can be delivered as a product is formed (S24). 在非水电解质二次电池的制造方法中，形成卷绕形电极体(S10)，并通过冲压加工成形为扁平状卷绕形电极体(S12)。将扁平状卷绕形电极体和盖体连接(
