A stacked electric double layer capacitor includes a capacitor unit, an aluminum laminate film, and a current collector terminal. The capacitor unit includes a pressure plate, and a current collector plate arranged inside the pressure plate. The aluminum laminate film wraps the capacitor unit, and includes a periphery that defines and surrounds a hole at a side surface of the capacitor unit. The current collector terminal is L-shaped, and includes a contact portion in contact with the current collector plate, and a terminal portion arranged perpendicular to the contact portion, wherein at least a part of the terminal portion is exposed through the hole of the aluminum laminate film, and connected to an external circuit, and the terminal portion is heat-welded to the aluminum laminate film. |
