To provide a structure providing compatibility of low NOx and combustion stability in gas-turbine combustion equipment.

The gas-turbine combustion equipment is characterized by that in a combustion chamber sidewall face of an air hole plate, an inner circumference sidewall face is positioned in a combustion chamber downstream side than an outer circumference sidewall face, and a connection part wall face is slanted with respect to an axis so as to reduce a radial distance from the air hole plate axis of the connection part wall face connecting the inner circumference sidewall face and the outer circumference sidewall face in a downstream side in comparison with a combustion chamber upstream side.
