Plate-like fins have notches longer than a longitudinal axis of flat tubes that are placed in the notches. The plate-like fins also have bend portions that are located on projections projecting toward the edges more than the ends of the flat tubes, are formed by bending part of the plate-like fins, erect in a stacking direction in which the plate-like fins are stacked, and are in contact with adjacent ones of the plate-like fins. The height of the bend portions in the stacking direction is the length of a predetermined spacing.
