Abstract
The present invention provides an electric double layer capacitor. An electric double layer capacitor element sandwiches a separator between a cathode and an anode, arranged inside a container comprising a concave shaped containing portion and lid. A first conductive layer on the inner bottom face of a containing portion is covered by an insulating layer, and opening portions formed on the insulating layer penetrate to the first conductive layer. A second conductive layer is formed on the insulating layer and inside the opening portions, and is connected to a cathode through a conductive adhesive. The first conductive layer penetrates through the side wall of the containing portion, and is connected to a connecting terminal. An anode is connected to a third conductive layer through a conductive adhesive, and a collector is connected to a connecting terminal by extending between the containing portion and the lid.
