Abstract
A rich-lean combustion burner has a supply channel through which a lean-side mixture is supplied to lean-side flame holes; and a supply channel through which a rich-side mixture is supplied to rich-side flame holes. The supply channels are partitioned from each other. A third plate member including a pair of plate parts which are bent to form a V shape at its lower end edge as a fold line is employed to form a central rich-side burner part. A slit part is partitioned and formed between side edges of a pair of first plate members on both longitudinal sides for forming lean-side flame holes on width-wise sides of the central rich-side burner part. With the lower end part in front, the V-shaped third plate member s inserted into the slit part, thereby being interposed between the first plate members.
