    • A method of manufacturing an electrode for a secondary cell capable of readily forming an active material layer only on a necessary portion of a collector by a method supplying raw material from a gas phase is obtained. This method of manufacturing an electrode for a secondary cell comprises steps of forming a mask layer containing a material reduced in adhesion to a collector due to a high temperature for forming an active material layer on a prescribed region of the collector, forming the active material layer on the collector and on the mask layer by a method supplying raw material from a gas phase and removing the mask layer and part of the active material layer formed on the mask layer. Thus, the mask layer is readily separated from the collector after the active material layer is formed by the method supplying raw material from a gas phase. Consequently, the mask layer and part of the active material layer formed on the mask layer are so readily removed that the active material layer is readily located only on a necessary portion of the collector.
    • 获得了通过从气相提供原料的方法仅在集电体的必要部分上容易地形成活性物质层的二次电池用电极的制造方法。 这种制造二次电池用电极的方法包括以下步骤:由于在集电体的规定区域上形成活性物质层的高温而形成含有与集电体粘合性降低的材料的掩模层,形成活性物质层 在集电体和掩模层上通过从气相提供原料的方法,并且去除掩模层和形成在掩模层上的部分活性材料层。 因此,在通过从气相供给原料的方法形成活性物质层之后,掩模层容易与集电体分离。 因此,形成在掩模层上的掩模层和活性物质层的一部分被容易地去除,使得活性物质层容易地位于集电体的必要部分上。
