A gas turbine combustor includes a main body with a combustion portion into which mixture of fuel and air is supplied. The gas mixture is burned through a catalytic reaction at a catalyst body arranged in the main body. The gas mixture passed through the catalyst body is introduced into a gas phase combustion portion provided in the main body. Between the catalyst body and the gas phase combustion portion is arranged a dividing unit which has a plurality of branch passages. The gas mixture passed through the catalyst body is divided by the dividing unit into a plurality of gas streams flowing through the branch passages. Each of the gas streams is mixed with fuel supplied from a fuel supply tube.
