Abstract
A plate body 11 of a combustion plate 10 is provided with no-burner port portion 13 where no burner ports 12 exist, and a burner port group 14 made up of a plurality of burner ports 12 is arranged in each region 15 of the plate body 11 surrounded by the no-burner port portion 13. A port diameter D of the burner ports 12 differs between the burner port groups 14, but the respective burner port groups 14 are made up of the burner ports 12 of the same port diameter D, and are arranged so that the greater the port diameter D of the burner ports 12 making up each burner port group 14, the greater the interval T between the burner ports 12 in the burner port group 14 becomes.
