(57) [Summary] [Structure] A sheet used for forming an anode or a cathode of an electrolytic capacitor, and a method for producing the sheet. This sheet consists of an electrically conductive substrate coated with an aluminum-based deposit, the method of manufacture of which consists in forming the deposit on the substrate by evaporating the aluminum in an oxidizing atmosphere. [Effect] Since a sheet having a large capacity can be obtained, the capacitor can be downsized. |
