Abstract: Provided is a graphite composite film that is capable of attaining both a measure against heat and a measure against electromagnetic noise and that is less likely to cause degradation of electromagnetic wave shielding properties. The graphite composite film includes a graphite layer, a first electrically conductive adhesive layer, and a metal layer containing a first metal disposed in this order. A first rust-proofing layer is interposed between the first electrically conductive adhesive layer and the metal layer, and a second rust-proofing layer is disposed on a surface of the metal layer opposite from a surface on a first rust-proofing layer-disposed side of the metal layer.

Abstract: An electrode foil for an electrolytic capacitor includes a metal foil having a porous part, and a dielectric layer covering a surface of a metal framework constituting the porous part. The dielectric layer includes a first layer containing an oxide of a second metal different from a first metal contained in the metal framework. The first layer has a thickness T1. The first layer contains at least one kind of additive element selected from the group consisting of carbon, phosphorus, boron, and nitrogen. The first layer includes a first region from an outer surface of the first layer to a center of the first layer in a thickness direction, and a second region from the center to an inner surface of the first layer. A content of the at least one kind of additive element in the second region is greater than a content of the at least one kind of additive element in the first region.

Abstract: An electrolytic capacitor has an electrode foil that includes a metal foil containing a first metal, a first dielectric layer disposed on the metal foil, and a second dielectric layer disposed on the first dielectric layer. A method for manufacturing the electrolytic capacitor includes subjecting a roughening treatment to the metal foil and forming the second dielectric layer on a roughened surface of the metal foil by an atomic layer deposition method. The second dielectric layer contains an oxide of a second metal. The method further includes forming the first dielectric layer containing an oxide of the first metal between the metal foil and the second dielectric layer by subjecting the metal foil to an anodization treatment.
