An electrode plate (1) for an electrolysis system (10), said electrode plate being made of sheet metal, in particular for producing hydrogen, has an active field (3) and a frame region (2) surrounding the active field, said frame region having a basic rectangular shape. The frame region (2) is formed on a base plane (E) of the undeformed sheet metal. The active field (3) has an embossed structure (6) in the form of individual embossed elements (14, 15, 16, 17) which are raised and recessed starting from the base plane (E), including a plurality of linear embossed strips (14, 15), which are positioned in an arrangement of rows and columns such that raised linear embossed strips (14) and recessed linear embossed strips (15) are formed in an alternating manner in the direction of the rows as well as in the direction of the columns, wherein all of the linear embossed strips (14, 15) of one row are inclined in an identical manner with respect to the longitudinal side of the active field (3) and a flow direction (DR) which is parallel thereto, and the linear embossed strips (14, 15) of the following row have an equal and opposite inclination.
