Combustion plate
There is provided a combustion plate in which the combustion resonant sounds and instability at the time of high-load combustion can be resolved and in which a large opening ratio of the flame holes can be secured. Flame holes of an equal diameter are formed evenly over an entire surface of a combustion region of a plate main body in such a positional relationship that adjoining three flame holes form an equilateral triangle. Provided that a flame hole group which is made up of six flame holes disposed in a positional relationship to form an equilateral hexagon and one flame hole in the center of the equilateral hexagon is defined as a unit flame hole group when disposed adjacent to another flame hole group across a large equilateral hexagon enclosing the equilateral hexagon, there is formed in the surface of the plate main body a bottomed hole.
