A separator for separation of opposite-polarity electrode plates in a lead-acid rechargeable battery includes two separator leaves connected together at rim areas which rest on one another to form a pocket which is open on one side for insertion of an electrode plate. A basic material thickness of the separator leaves at the rim areas increases from an outer edge of a rim area in the direction of the contact area of the separator leaf for an electrode plate, and the basic material thickness in the rim area adjacent to the contact area is greater than the basic material thickness in the contact area.
