An object of this invention is to accelerate further mixing of a fuel and air independently of a flow rate of the fuel. A gas turbine combustor comprises: a fuel nozzle for blowing out a gas fuel; an air nozzle plate with an air nozzle for jetting out the fuel and air into a combustion chamber after the blowout of the fuel from the fuel nozzle; and an obstacle formed inside the air nozzle; wherein the obstacle causes a collision of the fuel jet blown out from the fuel nozzle, and hence causes turbulence in an airflow streaming into the air nozzle. According to the invention, mixing between the fuel and the air can be further accelerated independently of the flow rate of the fuel.
