Abstract
The present invention provides an electric double layer capacitor that has less chance for internal resistance increase. For this objective, in this 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 lid and a concave shaped containing portion. On the inner bottom face in the containing portion, an insulating layer having a first conductive layer connected to a connecting terminal, and an opening portion penetrates to the first conductive layer are formed, wherein a second conductive layer fills inside the opening portion. Onto the insulating layer and the second conductive layer, a third conductive layer which laminates a first layer comprised of aluminum and a second layer comprised of carbon, is formed and connected to the cathode. The fourth conductive layer is connected to the anode, and also connected to the connecting terminal.
