PROBLEM TO BE SOLVED: To develop a combustion apparatus, performing burning in a stable condition with a constantly stabilized air-fuel ratio. SOLUTION: The combustion apparatus is constituted of: a combustion apparatus body 2; a blower 3; a fuel supply passage forming member 5; and a pressure regulator 6. The fuel supply passage forming member 5 for supplying fuel gas to each of burners 8a, 8b, 8c and 8d, has two fuel supply channels. The pressure regulator 6 discharges gas while decompressing it to a secondary pressure according to a pressure introduced through a signal pressure inlet port 32. The signal pressure is detected selectively from two positions on the discharge side of the blower 3. When a burning area is narrow, the signal pressure is obtained from the part with higher pressure. A gas discharge port 31 of the pressure regulator 6 is directly connected to the member 5, and the outlet side of the pressure regulator 6 is divided and connected to each fuel supply channel 5a, 5b.
