A corrugated fin for a heat exchanger characterized by constituting a tapered seal edge by bending and crimping a laminated flat surface formed at the tip of the corrugated fin. (2) At both side opening ends of the zigzag folded corrugated fin that is housed in the heat exchanger case body, every other side opening end is narrowed down to a triangular cross section across the entire width and formed at the tip. A corrugated fin for a heat exchanger, characterized in that both layers are bonded by interposing an adhesive or an adhesive film between the laminated flat surfaces. (3) At both side opening ends of the zigzag-folded corrugated fin that is housed in the heat exchanger case body, every other side opening end is narrowed down to a triangular cross section across the entire width and formed at the tip. A corrugated fin for heat exchangers characterized by a welded layer of aluminum formed on the entire face of the laminated flat face.
