PROBLEM TO BE SOLVED: To provide a combustor capable of improving the mixing operation of a fuel and the air even in the case of a large-scale coaxial jet flow type combustor, and a method for supplying a fuel to a combustion chamber. SOLUTION: The gas turbine combustor comprises a combustion chamber 8, a fuel nozzle 5 for jetting a gas fuel to the combustion chamber 8, and a vent 6 for jetting air and the gas fuel jetted from the fuel nozzle 5 into the combustion chamber 8. Since an air supply channel 12 is provided in a gas fuel channel of the fuel nozzle 5, the air flow from the fuel supply channel 12 is supplied to the combustion chamber 8 while being surrounded by a ring-like gaseous fuel flow.
