Abstract
A gas turbine combustor includes a fuel injection device provided to a combustion tube forming a combustion chamber on an inner side, and including: a fuel injection portion having a plurality of fuel injection holes which inject fuel in directions containing components perpendicular to an axial direction and a common fuel supply chamber which supplies fuel into the plurality of fuel injection holes; and an air guide portion which guides air to fuel injected from each fuel injection hole. The fuel injection portion has an air guide surface which guides air for combustion and is located frontward in the axial direction of the combustion chamber relative to the fuel injection hole. A fuel injection opening of the fuel injection hole is provided at a bottom wall surface of a stepped recess recessed in a step shape from the air guide surface.
