Abstract
An energy storage device includes an electrode assembly, a positive-electrode current collector, and an insulating sheet. The electrode assembly has a main body part and a connecting part projecting from the main body part and connected to the positive-electrode current collector. The insulating sheet has a sheet side surface part facing a side surface of the main body part, and a sheet extension part extending from the sheet side surface part. The sheet extension part is fixed to the electrode assembly.
