PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of unifying (uniforming) distribution of fuel concentration in the longitudinal direction of swirlers, and further reducing NOx. SOLUTION: In this gas turbine combustor in which the fuel is injected from fuel injection holes 26a, 28a to the air or air-fuel mixture flowing from an upstream side, and which has the plurality of sheets of swirlers 26, 28 for creating the swirl air-fuel mixture flow by applying turning ability thereto, turning ability application means 31, 32 for providing the air or the air-fuel mixture flowing into a flow channel formed between the swirlers 26, 28, with turning ability, are disposed near upstream sides of the swirlers 26, 28.
