To provide a sheet electrode having a small electric resistance which suppresses an oxide film formation on a collector surface by coating active material paste at one time on both the sides of the collector by a simple means, and drying the surface of the collector in a drying process without exposing the surface thereof to the air.
This sheet electrode manufacturing method has a coating process for coating electrode active material paste on a collector surface of a metal foil strip and a succeeding drying process for drying the active material paste. In the coating process, a sheet electrode 4 is passed in an opposite direction to the rotating direction of coating rolls 1 through the gap between two coating rolls 1(1L, 1R) reversely rotating each other, so that the active material paste supplied in a fixed thickness on each surface of the coating rolls 1 by a measuring mechanism is transferred to the both sides of the collector 4.
