Provided is a combustion plate wherein combustion resonance or instability during high-load combustion can be overcome, and a high opening percentage for flame holes can be ensured. Flame holes (12) having the same diameter are evenly arranged over the entirety of the combustion area of a plate main body so that three adjacent flame holes are positioned so as to define an equilateral triangle. Flame hole groups, each of which is comprised of six flame holes (12) positioned so as to define a regular hexagon (13) and one flame hole (12) positioned at the center of the regular hexagon, are adjacent to each other across large regular hexagons (14), each of which surrounds a regular hexagon (13). Each of the flame hole groups is defined as a unit flame hole group, and bottomed holes (15), each of which is coaxial with the flame hole (12) positioned at the center of each unit flame hole group, are formed in the surface of the plate main body. Furthermore, if a predetermined diagonal direction or a predetermined opposing direction of the opposite sides of each regular hexagon (13) is defined as a column direction, at least one of twelve flame holes is closed, said twelve flame holes positioned on each large regular hexagon (14) surrounding each unit flame hole group that belongs to a selected column which is selected from among the columns of the unit flame hole groups arranged in the column direction and is spaced from apart from other selected columns by a predetermined distance in a direction perpendicular to the column direction. |
