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.

A method for fabricating an electrode for lithium secondary battery formed by depositing a thin film composed of active material capable of lithium storage and release, on a metallic foil to be used as a current collector, in which the surface of the metallic foil is roughened through wet-etching and then the thin film is deposited on the roughened surface.

Method for fabricating electrode for lithium secondary battery

A method for fabricating an electrode for lithium secondary battery characterized by applying a tension to a metallic foil so as to pull an area of the metallic foil on which a thin film composed of active material is deposited, from the both sides in the direction of longitude, when depositing the thin film on the metallic foil serving as a current collector.

A photovoltaic element having improved conversion efficiency and improved light confining property as well as a method of manufacturing the photovoltaic element with superior productivity are provided. The photovoltaic element includes an n type single crystal silicon substrate having first and second main surfaces, an intrinsic amorphous silicon layer formed on the first main surface, a p type amorphous silicon layer formed thereon, a conductive thin film formed thereon, a collecting electrode formed thereon, an intrinsic amorphous silicon layer formed on the second main surface of n type single crystal silicon substrate, an n type amorphous silicon layer formed thereon, a conductive thin film formed thereon and a back electrode formed thereon. At a peripheral portion of a laminated portion including the intrinsic amorphous silicon layer formed on the first main surface of the n type single crystal silicon substrate, the p type amorphous silicon layer and the conductive thin film, a trench deep enough to reach at least the intrinsic amorphous semiconductor layer is formed.
