Gas turbine combustor and gas turbine

A gas turbine combustor comprising:

• a combustion cylinder which includes a combustion chamber inside and in which a plurality of through-holes open to the combustion chamber are formed;
• a housing that is disposed on an outer peripheral side of the combustion cylinder and that defines an acoustic attenuation space that communicates with the combustion chamber via the through-hole;
• an air hole plate in which a plurality of air holes are formed and which is positioned on an upstream side of the combustion cylinder;
• a plurality of fuel nozzles that correspond to the plurality of air holes, respectively;
• an air passage that is provided between an inner peripheral surface of the combustion cylinder and an outer peripheral surface of the air hole plate and that extends in an axial direction of the combustion cylinder;
• and
• an air supply flow path for supplying air flowing on an outer side of the combustion cylinder to the acoustic attenuation space,
• wherein at least one of the plurality of through-holes is provided directly below the air hole plate in the axial direction.
