摘要:
The present invention relates to an electrochemical capacitor, and provides an electrochemical capacitor which has a fully lowered internal resistance and can yield excellent charging/discharging characteristics. The electrochemical capacitor of the present invention is mainly constituted by an anode and a cathode which oppose each other, an insulating separator disposed between the anode and cathode adjacent thereto, an electrolytic solution, and a casing accommodating them in a closed state. The anode contains a substantially spherical carbon material having an electronic conductivity as a constituent material, whereas the cathode contains a fibrous carbon material having an electronic conductivity as a constituent material.

An electrochemical device comprises a laminate including a first electrode layer, a separator layer, and a second electrode layer laminated in sequence; an electrolytic solution infiltrating the laminate; and a resin part covering an outer periphery of the laminate. The second electrode layer has an area smaller than the area of the separator layer and the area of the first electrode layer. The surface of the separator layer opposing the second electrode layer is provided with a noncontact part kept away from the second electrode layer. The noncontact part is formed like a ring along the outer periphery of the separator layer. The resin part further covers the noncontact part of the separator layer.

A series of optical recording media is provided to reduce a burden on an optical pickup by introducing a standardized idea among a plurality of optical recording media. In the series of optical recording media, optical recording media are of a plurality of types, each optical recording medium including a plurality of planar recording and reading layers with no projections and depressions for tracking control, and a servo layer with projections and depressions for tracking control. The plurality of optical recording media have different numbers of stacked recording and reading layers, and the positions of the servo layers with respect to the corresponding light incident surfaces are standardized among the plurality of optical recording media.
