Method of manufacturing electrode substrate

摘要

An electrode substrate comprises a backing substrate carrying thereon a metal electrode layer and/or a recording layer, the layer or layers having a smooth surface area with a surface roughness of less than 1 nm by more than 1 mum2. The smooth surface of the metal electrode layer and/or the recording layer is formed by firstly forming the layer on another substrate having a corresponding smooth surface and then peeling the another substrate off the layer after the layer is bonded to the surface of the backing substrate, whereby the smooth surface profile of the another substrate is transferred to the surface of the layer formed on the backing substrate.
