Abstract
An electrochemical device electrode has a current collector, alkalescent resin layers, conductive layers, and active material layers. The current collector is an acid-etched metal foil whose surface has concavities. The alkalescent resin layers are formed and desiccated inside the concavities and exhibit weak alkalinity. The conductive layers are formed on the current collector and the alkalescent resin layers, contain conductive material, and are electrically connected to the current collector. The active material layers are formed on the conductive layers.
